Full textThe cost of building constructions today is high and requires the industry to become more efficient. The search for continuing streamlining have brought the utensils into line with the development. Concerning constructions the progress during the last 25 years has extended from pen and paper, to buil-int computerized three-dimensional models. At present the majority still utilize two dimensional based programs, for example Autodesk Architectural Desktop, ADT, an AutoCAD based software from Autodesk. Nowadays the programs are objectbased, i.e. construct three-dimensional geometry of the building structure. The program then plots 2D structural blueprints from the model with subsequent information of the various components. An example of such software is Tekla Structures. The arguments for and against concerning effects and differences in the duration of client time consumption that exist in the use of the various softwares will be evaluated in this report. Tekla Structures is a software adjusted for the design of construction blueprints and lends itself very well to buildings with steel and concrete structure. Since most of the construction and planning designers work with DWG files, a unified way of working is desirable, where ADT might constitute as a plausible candidate. A great advantage of Tekla Structures is that the software within the model contains the complete information necessary for design, manufacture and assembly. The blueprints generated are always updated and current.

Full textThe building industry is going trough a transitional stage, from 2D to 3D. BIM, as a working method, and 3D models are becoming more common. In bridge project however, the demand for 3D models is low. At WSP in Stockholm the 3D modelling program Tekla Structures is widely used in several departments. There is a desire to expand the usage of the program also when it comes to bridge planning. To make that possible a bigger request by the customers is required. The purpose of this thesis is to evaluate Tekla Structure as a tool from a customer perspective and to analyse the customer values by using Tekla models. To shed light on this issue interviews have been made with different customers of WSP. The customers’ needs and their reflections on BIM and Tekla Structures in bridge projects are mapped out and analysed. Aspects reached by the customers have served as a basis for analyse of a 3D model, built up in Tekla Structures, as well as two bridges – already modelled in the same program. The analysis shows that there is a big customer value by using Tekla models in bridge projects, but to enable management models great efforts are required. An evaluation of the software also shows both strengths and weaknesses. In the following pages the result is presented.

Full textToday, BIM (Building Information Modeling) is applied as a leading tool in structural design and modeling and enables solutions that are sustainable and optimized between different disciplines to effectively manage information flows. In connection with transfers between software’s a neutral file format, IFC (Industry Foundation Classes), is used. This file format is exported from the 3D-modeling program Tekla Structures. The purpose of this thesis is to examine the reason for missing information on IFC exports from Tekla Structures. The study includes a case study, comparative study and interviews In the case study, the settings for an IFC- export are studied from a complex 3D- model in Tekla Structures. The comparative study concerns two coordination programs Solibri Model Checker and Navisworks Manage, which are compared against each other. What is examined is how IFC- files are suitable in the coordination programs. The interviews have given clear guidelines during the work. The results indicate that the causes of missing information in IFC -files are the human factor and the lack of knowledge of the settings of an IFC- export. Additional to the results that was achieved are the comparison between the coordination programs shows that both programs are suitable for the IFCformat. The difference between the coordination programs is how one of them signalized the format better than the other Regarding the results, the human factor is crucial for the information loss. The human factor has shown that the lack of communication and knowledge of IFC- exports is a reason for the information loss. Through the comparative study, it has also been shown that Solibri is better suited for IFCexports from Tekla Structures.

Full textWhen WSP Group in Norrköping creates building models they use two programs: TEKLA Structures and AutoCAD Architecture. One of the reasons for using two programs is that the reinforcement tool Impact Reinforcement in AutoCAD Architecture works better than the reinforcement tool in TEKLA Structures. If there is a need for reinforcement in a TEKLA Structures model it is exported to AutoCAD Architecture where the reinforcement then is constructed. I have therefore done a research on the differences between the two programs. The result is that Impact Reinforcement is easier to use while more time is needed to learn TEKLA Structures. TEKLA Structures could make the work more effective with the right knowledge.

Full textDigitalization gives opportunities to new and more efficient workflows within all different type of industries. New software programs and add-on features are often released and there is a lot of new information to process for the people adjusting to these new software programs and add-in features. Even though these digital solutions have benefits in both cost- and economy point of view it can be difficult to change the workflow and implement new routines on the workplace. Tekla Structures is a BIM-tool (building information modelling) owned by Trimble which is used frequently within the building industry. The purpose with this report is to explore and compile the possibilities with Trimbles newly released tool Tekla Bridge Creator in bridge projecting. Today Tekla Structures can be used together with Rhinoceros and its extension Grasshopper through Grasshopper-Tekla Live Link (a more detailed description of the software programs can be found in the reports Theory chapter) but the workflow can be seen as complicated and requires good knowledge with the software program. This report describes the designing of a bridge model in Bridge Creator and thereafter a similar in Grasshopper. The workflows will be compared to give an understanding for Bridge Creator and an opinion for how it best can be applied in bridge projecting and if it can be of use for the person with the desired goal he or she has. Bridge Creator has shown to have a lot of limitations concerning modelling of parametric adjustable bridge-models, which is possible in Grasshopper. In short summary this means the possibility to choose a specific parameter, for example the total length and width of the bridge, and the whole model quickly adapts when these changes. For example, if a bridges total length changes, the columns, railings and similar building parts need to be changed manually. In Grasshopper these parts can adjust automatically so if the bridges length is changed these parts follow the length change. It’s hard to say if Bridge Creator is to recommend or not, it depends on the user’s previous knowledge with bridge design, which bridge constructions that are created, how adjustable they shall be and how big value that lays in being able to reuse in new projects. Bridge Creator is furthermore in an early development phase and is going through improvements over time which means that it can’t be excluded that Bridge Creator in the future can be used like Grasshopper to create parametric adjustable bridge models.

Full textThe development of BIM has in recent years gained momentum and many countries, including Sweden, have begun a process towards common structure in the sector of construction by standardizing information and processes (Nilsson, 2013). This development provides new opportunities for participants in the process of construction but also problems when the intensive IT- development meets a seemingly conservative industry (Statskontoret, 2009:6). The aim of this thesis is to design a modernized working process for the structural engineer that integrates BIM tools in the design process. An understanding of how the constructional engineer's work looks today is determined, and the possibilities and difficulties that the designer is experiencing. The findings in this study were that, despite the intensive development of BIM in recent years traditional processes are still applied, since an understanding of a higher initial effort does not yet exist. Increased demands are also put on the structural engineer's technical competence in structural engineering since it´s harder to "cheat" in the object-based models. The qualitative study demonstrated a conservative approach where the development of the structural engineer's role by means such as finished components from different vendors in Tekla Structures was seen as more problematic than beneficial. It also emerged that the most effort should be in the coordination of the project, in which more than clash detector tests should be taken into consideration and that the review should take place at an earlier stage and performed more consistently. In the practical use of Tekla Structures several opportunities to review and coordinate a project was found. The need for standardized BIM as concretized in the theory section was also confirmed by the respondents in terms of the desire for a common structure in the models. The work resulted in a working model for how the structural engineer should work with BIM and the conditions requested to allow this approach. An important part of this is to define a well-structured and clear way of working that is achieved through clear goals. Central to each BIM project is to appoint a BIM Coordinator whose task is following up the work towards the defined goals and ensuring united design among the workers. BIM requires a comprehensive understanding of the design to meet the new requirements.

Full textIn this thesis, a study has been conducted to develop and compare methods of modeling curved stringer made of steel with complex geometries in the Tekla Structures program. The delimitation of the study has been to compare two methods: Method 1 uses the Complex Polybeam Creation tools in combination with Surface Generation Between Polybeams in Tekla, and Method 2 uses the tool Spiral Staircase. A spiral staircase from the project Patienten and Princeton, Sankt Eriks Eye Hospital in Hagastaden, Stockholm, has been used to test the complex geometries that this spiral staircase entails. Based on this, Tutorials of the two methods have been created, so that the reader can easily follow and implement the same steps. The result of this thesis is that both methods work for modeling, depending on the type of geometry that is created. After modeling with the tool Spiral Staircase, correct manufacturing drawings of the horizontal plates could not be obtained, unlike Method 1. The conclusion of the study is that with only rapid modeling of circular geometries as well as production of manufacturing drawings for vertical curved plates, Method 2 can be used with advantage. However, in the production of manufacturing drawings of complex and non-circular geometries, Method 1 is best suited.

Full textNew methods for project designing in the building construction industry have been developed by introducing modern and powerful BIM tools. Several of today’s constructions are designed according to three-dimensional principles.Tekla Structures is a powerful BIM tool that is capable of managing both house and infrastructure constructions. Despite this, the program cannot handle bridges with a horizontal and vertical curvature efficiently. The designers must instead rely on several other applications to manage complex bridge constructions.In order to use the advantages of Tekla Structures, the software needs to be evolved or complimented by other third party softwares. This project aims to integrate new working technics and introduce a method based on parametric design in Tekla Structures. Such form of modeling enables the modification of parameters to a desired model for the user.A script is created through a visual programming extension that generates a parametric based bridge models. The bridge type in this project was designed, is an integral bridge.The project has proved that parametric based design is more effectively and a solution to manage bridges with horizontal and vertical curvature.

Full textWithin the construction industry, there is a lot of discussion around BIM (Building InformationModelling). There is a need to move away from customized 2D-drawings and instead focus oninformative models which can be used throughout the whole cycle of construction. This developmenthas been ongoing within house construction, but this approach is harder to implement within thefacility sector.The difficulty in implementing a more BIM-oriented approach within construction is partly due tosoftware currently not being fully developed to create informative and reliable models of constructionswith complex geometries, such as bridges.Since Trafikverket, the largest construction developer within Sweden, has started to place a largerdemand on 3D there is a need for both technology and human resource to develop.The aim of this dissertation is to present a case study investigating the suitability of the software TeklaStructure and AutoCAD Civil 3D to perform a 3D-model of a double-curved bridge. The two pieces ofsoftware will be contrasted in a final comparison whereby both pros and cons will be presented.The study has made it clear that BIM is not just about creating an informative model, but it is alsoabout an approach which has the ability to completely change the construction sector to work morecollaboratively and effectively.The comparison between the two relevant software in this study shows that they both have strengthsand weaknesses and are suitable for our purpose. However, they differ in how detailed models theycan create and how well they have the ability to work with BIM to a greater extent.

Full textTill grund för detta examensarbete ligger en ineffektiv process, samt dubbelarbete som idag utgör arbetsgången vid CAD-projektering för konstruktörer hos Structor i Karlstad. Målet med examensarbetet är att genomföra en kompatibilitetskontroll av 3D-modelleringsprogrammet Tekla Structures 15.0 mot analys- och beräkningsprogrammen Autodesk Robot Structural Analysis Professional 2010 samt Strusoft FEM-Design. Syftet är att med hjälp av kompatiblitetskontrollen utgöra vilket av programmen Autodesk Robot och FEM-Design som bäst lämpar sig att köras tillsammans med Tekla Structures utifrån valda faktorer. Två äldre examensarbeten används för att få en uppfattning om FEM-Design.
För att undvika det omfattande och tidskrävande arbetet med att skapa två modeller, en grafisk samt en analytisk modell, finns en lösning. Genom att skapa den grafiska modellen i Tekla Structures 15.0, vilket sedermera genererar den analytiska modellen, och sedan exportera den via länk till Autodesk Robot Structural Analysis 2010 behövs bara en modellering. Ett arbetsmoment, som förut inneburit ytterligare en modellering i analysprogrammet, undviks härmed. Medveten modellering, det vill säga kontinuerlig kontroll av den analytiska modellens utseende i Tekla, krävs för mest fördelaktiga resultat. Detta bör finnas i åtanke under hela arbetsprocessen. Det är i slutändan alltid projektören/konstruktören som styr hur Robot i sin tur kommer att behandla modellen som skickas från Tekla.
Laster och lastkombinationer går att justera i både Tekla och Robot. Dock anses det, för en van Teklaanvändare, vara smidigast att hantera detta i Tekla. Om detta sker i Tekla behövs ytterligare inställningar i Robot aldrig göras. Robot utför då endast analysen och bearbetar de resultat som analysen utgör. De resultat som återfinns går att behandla i Robot och redovisas på sätt som är relevanta för respektive användare. De grundläggande resultaten, så som största påverkande moment och tvärkraft, går att importera tillbaka till modellen i Tekla och hamnar då under respektive profils attributinställningar.

Full textThis thesis intends to answer whether Tekla Structures can function as a suitable 3D modeling software for the department of Transportation & Mobility within Grontmij Sweden. Given positive experiences from Building Information Modeling, so called BIM, and 3D modeling in other areas of Grontmij there was a desire to optimize the work processes of the department with the latest knowledge in the field. This report focuses on practical modeling of a case study, based on one of Grontmij’s previously conducted construction projects. To ensure a representative case study, a heavily reinforced slab-frame bridge was selected which was considered to have a complex geometry that potentially would be advantageously represented in 3D. The process of creating the 3D model and associated drawings was divided into three stages; modeling, detailing, and visualization. The construction of the 3D model demonstrated unique advantages and disadvantages in each stage where also this thesis’ work plan was compared with the case study’s time plan. The results showed that the steps modeling and detailing (reinforcing) showed benefits in relation to the time spent. For the visualization step, i.e. the creation of 2D drawings according to the terminology of this report, the conclusion was the opposite. Grontmij’s Transportation & Mobility department is therefore recommended to selectively integrate Tekla Structures’ advantages into their future work process and continue to evaluate the program in other related fields.

Full textDetta examensarbete har granskat modelleringsprogrammet Tekla Structures och besvarat frågan om huruvida det kan fungera som ett lämpligt modelleringsprogram för konstruktionsavdelningen på Bjerking AB i Uppsala. Metoden som har använts i arbetet är en fallstudie av ett tidigare genomfört projekt med befintliga underlag att utgå ifrån. Avgränsningen i studien har varit att endast undersöka användbarheten i grundkonstruktioner av platsgjuten betong. Arbetet undersökte tre huvudområden inom projekteringsprocessen. Det första var att modellera betongelement sedan att modellera armering och till sist framtagning av ritningar. Eftersom Autodesk Revit var det befintliga modelleringsprogrammet på avdelningen genomfördes utvärderingen som en jämförelse mellan de två olika programmen. Förutsättningen var att alla tre hvududelarna skulle göras i ett och samma program. Resultatet visade att Tekla Structures har stor potential inom området betongmodellering, och det är ett lämlpligt modelleringsprogram att använda för projekt som innefattar grundkonstruktioner i platsgjuten betong. Studien har även visat programmets fördelar med att 3D-modellera armeringen inom dessa typer av projekt.

Full textThe use of different BIM tools is becoming increasingly frequent in the construction sector. Information exchange of 3D models between the various actors of the project takes place continuously during the design phase. Because different actors use different software, an openfile format is needed for the delivery of 3D models. IFC is a neutral file format that enables information exchange between different disciplines and coordination of BIM models. This exam work is a preliminary study of qualitative and quantitative variety, with the aim of developing an internal working method for quality assurance of IFC model delivery. The qualitative parts include interviews. Interviews are made to gain an understanding of what the employees at WSP Byggprojektering Göteborg have in mind about different programs and management of IFC. It has given the authors a deeper insight and understanding of the benefits and challenges that respondents encounter, which are highlighted in the section results. Apractical part is included in the degree project. During the practical steps, it will model in Tekla Structures and Revit to then analyze the models with the help of the review programs Solibri Model Checker and Navisworks Manage. Two review methods are created in this thesis, a visual review and an Excel report. The visual inspection method involves visually reviewing the IFC model in the same review program as the coordinator. The second method is a prototype that compares different reports from the respective software.The conclusion in this report is as follows: • Human factor in the modeling and use of correct tools when exporting to IFC. • The IFC format and the ability of the various programs to interpret the IFCinformation may in some cases fail for non-standard geometries. • Review programs can interpret the IFC model differently.

Full textThe purpose of this project has been to study which requirements apply on wooden bridges from a design perspective, observing both external requirements and internal requirements from the company Martinsons. Based on these requirements measures would be proposed to adapt Martinsons Tekla-template model for the design of timber bridges. The theoretical part of the project has, as a starting point been conducted by studies of the Transport Administration's requirements on wooden bridges. Discussions with designers working with wooden bridges have also been conducted to get an understanding of their experiences and opinions. Furthermore, a number of previously constructed wooden bridges have been studied in order to find areas in need of improvement. With this background, it then examined which measures were feasible in Tekla. Several measures that would aim to improve the drawing quality and comply with the applicable requirements was produced and declared in the project. Measures aimed to streamline the modeling and drawing creation was also proposed. The measures proposed should enhance Martinsons Tekla-template model in a significant way, but shall in no way be considered as a definitive solution in the quest to meet the requirements concerning the design of wooden bridges. The projekct made it clear that it is not reasonable, or even feasible, to adjust the template model to meet all requirements, some adjustments must be done in each project. It also became clear that it would be good to open a dialogue with the Swedish Transport Administration to make sure what their requirements are so that Martinsons can comply with them in an effective way.

Full textThe purpose of this thesis was to study and implement a script for a parametric modelling of a bridge in Rhinoceros 3D Grasshopper. The script was done with visualized programming components and the structure was a slab frame bridge. Parametric design is a tool that create models with the use of different prerequisites called parameters. These parameters can be changed directly in the script which in turn changes the model. This makes the editing process of the model easier and allows for greater variations of the same structure to be handled within the same script. In this project, Tekla Structures was used which is a powerful BIM tool that can be used for design and analyses of various structures. Rhinoceros Grasshopper was connected to Tekla Structures with their own plugin, called Tekla live link. Several interviews have been conducted with experts and experienced people in the subject for input on how the programs are used today in the building branch as well as how far parametric design has come. The results of this thesis shows that parametric design is useful mostly when it comes to redactions of an already existing model. The designed structures are programmed in such a way that all their different components are connected. This allows for edits and redactions to be made on one specific component without having to change or redesign the rest. This saves time during the designing part of a project. Although, when it comes to smaller scaled projects or structures with simple geometries,using programs such as Tekla Structures is still faster and easier as opposed to using Rhinoceros Grasshopper. This is because programming and creating a script can take a lot of time and is very complicated at times. However, the result of this thesis shows that it could be wise to use parametric programming when it comes to larger projects and/or more complicated structures.

Full textIn this study, the BIM-compatible program Tekla Structures is compared with traditional 2D-CAD when designing the foundation for two different construction projects. In the two different projects, Årevägen and project Bergbanan, 2D-CAD was used when drawings and reinforcement lists were created. In this study, the same drawings and reinforcement lists were created instead using BIM and Tekla Structures. The study is based on drawings, reinforcement lists and a summary of the number of hours spent in the design of the foundation in the two different projects. The purpose of the study is to investigate improvement opportunities in the design phase when using BIM programs compared to traditional 2D CAD programs. The results will show if benefits, in terms of time gains may exist during the design phase. The study approach is based on quantitative methodology and the variables studied were time gained or time lost in hours. The study was limited to the foundation only in the two projects, and no account is taken of financial consequences or how other participants in the projects are affected by the time differences that occur. The study examines the time difference that appears when drawing up construction drawings for the foundation of each project, the time difference that appears in the revision of the drawings and also the time difference that appears when establishing and revising the reinforcement lists. The study's results show that early in the design phase, more time and resources are needed when BIM is used in comparison with 2D CAD. This result is also reflected in previous studies in the field, the benefits in terms of time savings with BIM instead occur during the later part of the design phase when the drawings are to be revised. When establishing and revising the reinforcement lists in both projects, time gains appears when using BIM. The result leads to the conclusion that BIM and traditional 2D CAD should be compared from an overall perspective. BIM is 3D modeling but also represents a way to create and process information, and the major advantage of BIM is the information stored in the BIM model and how the information can then be used. Finally, we conclude that BIM shows great potential for streamlining the design phase, in addition, the key to time gains is to utilize all the information that can be linked to a BIM model effectively.

Full textA design process of a construction can often be divided into two parts, structural design anddrawing. The structural design is made with current standard requirements for theconstruction while the drawing has its own standard requirements along with the results fromthe dimensioning to follow.Even if 2D- drawing still is common in design of a project, BIM-modelling has become morefrequently used and the value of storing information in a model is see more and more as abenefit in a project.The BIM-modelling is based on parametric design of objects and there are actually no limitsto which parameters that should be a part of an object.One of the most recent developments in the design process is the visual programming whichgives users the opportunity to guide parameters in a BIM-model through a visual scriptconnected to the BIM-modelling tool.This work is aiming to show how a script can push the modelling by using project specificinput and perform structural design of load bearing members integrated in the script. With theuse of the script, results can also be verified in another software.Result is showing that it is possible to create a structurally designed model by using only afew object specific inputs and that parameters can be controlled in a script made with visualprogramming.

Full textIs the new technology always the best? This final project tries to determine if BIM is the melody of today, or if traditional 2D drawing is recommended. Perhaps a compromise is necessary, utilizing both methods.
In order to answer this question, different views from the industry have been retrieved through reports, producers of software and users. The approach has consisted in building a 3D model of the school Råslättsskolan, house 01, along with interviews with people involved in the building process.
When working in 2D it is hard to include the third dimension, mistakes are done and collisions happen that must be corrected, in most cases at the construction site. BIM is an incredible help since the model allows you to detect collisions and correct them. Another time when models are preferred is when you need production plans, for example, different steel details that will be joined together at the work shop before shipping to the construction site.
Skanska and NCC, in densely developed urban areas, already require BIM today, something that most likely will be customary within the nearest future. It is not hard to understand that more and more clients require BIM when you realize its advantages. With the correct method, these 3D models can minimize risks of errors, optimize the production and save money.When it comes to introducing BIM today at BGK the students can’t do anything but make a recommendation. The improved quality, the future prospect and that the advantages of BIM is not depending by project size will make it attractive for BGK to begin a transition already today. BIM is the melody of the future, not the only song being sung, but clearly the strongest one.

Full textWhile carrying out structural design work, it is important to take into consideration the environmental impacts and costs throughout the life time of the structure. This is done through life cycle assessment (LCA) and life cycle cost analysis (LCC analysis), respectively. LCA addresses the environmental aspects and potential environmental impacts throughout a product’s life cycle i.e. from cradle to grave. An LCC analysis summarizes the investment cost and costs for operation and maintenance during the life time of the product. BIM 3D modeling tool are used for modeling several different types of buildings and civil works. Ideally, digital information readily available through these powerful BIM tools, should be reused to perform LCA and LCC analyses. It would also be beneficial if it was possible to connect it to a company’s internal systems for instance in this study, the Swedish Transport Administration's “Klimatkalkyl” (a tool based on the method for LCA). The purpose of the thesis project is to integrate cost and environmental impact into the early design phase through an automated connection between BIM programs and LCA / LCC tools. By automating this process, optimization of structures can be made more efficient. An Excel sheet has been created through programming in Visual Basic for Applications (VBA) which retrieves quantities from either Tekla Structures, Excel or manual input and then generates LCA and LCC reports. These have then been compared with existing LCA and LCC analyses to ensure the program's quality. The result of the work shows that produced LCA and LCC reports can contribute to a more efficient structural design process for optimizing structures regarding environmental impacts and investment cost. The Excel sheet's user-friendly structure also enables people with limited knowledge in LCA and LCC to make more sustainable choices when undertaking structural design tasks. This helps to promote sustainable thinking in companies and encourages employees to work towards a common goal of a carbon-neutral infrastructure sector.

Full textIn connection with the digitalization's entry, the companies has begun to apply new improved BIMtools to streamline the constructor's work. With the help of the implementation of graphical thirdparty applications, the BIM-tools can achieve increased functionality. An example of such a program is the third party applications Grasshopper linked to the Tekla Structure, which creates so called computational design, which means that the model's data is controlled and accessed by the external programs. The Bridge and Tunnel department at Ramboll wants to become, like many other consulting firms, more BIM oriented. However, there is no estimate of total timesaving and utilization of the implementation today. The purpose of this thesis project has been to come at a conclusion that provides support in decision-making regarding which types of projects that parameter-controlled models may be suitable for. By building an automated script for a retaining wall, this study has shown the connection between the software Microsoft Excel, Rhinoceros-Grasshopper and Tekla Structures. With this application, one has succeeded in creating an easy-to-use interface. Furthermore, one has compared the finished script in Grasshopper with a model in Civil 3D where the assumption that one can gain time by having a finished script. It has also been possible to draw conclusions under which conditions it is suitable to use parametric modeling and automation that points to early stages in design and standard constructions.

Full textBackground: The Swedish Parliament has legislated a long-term environmental objective that Sweden as a nation should be climate neutral by 2045. In Sweden, the construction and real estate industry accounts for about 18% of the total national greenhouse gas emissions. The growing need for expanding construction makes it important to take into account the increasing climate impact of production of building materials, construction and maintenance. Documentation of the construction project's carbon footprint in terms of life cycle analysis (LCA) begins to be requested by several public and private clients. Creating an LCA-report today is a very time and resource consuming process. There is no connection between calculation and planning of climate impact, based on an LCA and the technical project planning which constitutes an obstacle to reach the climate targets.Swedish construction companies store project data in various IT-based production- and planning systems, eg. calculation systems, digital design programs (CAD, Computer Aided Design), internal LCA tools, etc. The Swedish Transport Administration (Trafikverket) sets demands on both delivery of construction documentation in a digital format and reports of reduced climate impact in their projects. But currently the procedure lacks an effective way to transfer project information, such as building materials and their amount of construction parts, from CAD tools to LCA software.The new building classification system, CoClass, offers a new way of organizing digital project information in CAD tools. Initiatives from the construction industry are underway to investigate whether the use of CoClass can simplify the transfer of project information from digital models to LCA software.Purpose: The purpose of this report is to develop a process of parameterization in digital models in accordance with the new CoClass system and investigating ways of transferring information in a digital way to an LCA software.Method: In this report, the approach has been several semi-structured interviews. The interviews ware targeting building constructor and climate/LCA coordinators. In the work based on information from the interviews a parametrization of a concrete bridge was performed in a CAD-software, Tekla and further the information was transferred to LCA software, GaBi.Conclusion. The results of the interviews and the test shows that it is technically possible to use CoClass to parameterize the information in digital models regarding to LCA, today. There is currently no incentive for clients, entrepreneurs and consultants to start structuring their digital models according to the CoClass system. But the increased demand requirements for reducing climate impact in construction projects can become a spur for different market participants to switch to the CoClass system. Implementation of the CoClass system in the construction industry will create new business opportunities with climate-efficient constructions and technical designs, which will support the fulfillment of Sweden's climate efficiency targets.

Full textThe use of the steel mesh as reinforcement of asphalt pavements to combat reflective cracks by reflection is an alternative used since 1980 in European countries. A review of the literature on the use of the steel mesh in the rehabilitation of asphalt pavements shows that its use prevents the appearance of cracks acting as a barrier against its propagation, offers resistance to shearing especially under high tensions and also improves the resistance to fatigue contributing to the longevity of the pavement. However, the potential if its use has been little investigated in Brazilian highways. In this context this project is to develop a new technology for road construction and rehabilitation. The idea is to use steel mesh reinforcement in asphalt roads in order to make road structures more cost effective by improving the lifetime of new constructed roads and by developing an optimal rehabilitation method for existing roads. For this, a research was performed aiming at the analysis of its performance in an experimental section located on the highway SP-354, in the State of São Paulo between the cities of Campo Limpo Paulista and Jarinu, based on the best international practices, using observation of its behavior in the field and laboratory, analysis by means of resilient modulus tests and calculations by backcalculation to verify the effect of the insertion of the screen, still proposing, a methodology of asphalt pavement design considering the range of integrated resilience module values with the screen and the structural deflection reduction factor (K) admissible for reinforcement projects. It was concluded that this reinforcing technique has potential for improvements crack propagation post-cracking behavior and permanent deformation in the asphalt concrete surfacing layer, with a ten fold increase on fatigue life to be expected. A model was developed that may be employed for pavement design modifying a model based on the use of conventional fatigue laws for the asphalt concrete, if the grid is positioned at the tensile zone of the surfacing layer. Finally, it was verified through a technical / economic study that the incorporation of the steel mesh in flexible pavements is an effective alternative and of adequate technical and economic viability.

As estruturas de concreto armado vêm se tornando cada vez mais esbeltas, aliadas ao menor tempo de execução das edificações e aos menores prazos de execução da fixação da alvenaria na estrutura, cada vez com mais freqüência observa-se a formação dos estados patológicos nas alvenarias. As estruturas de concreto armado apresentam progressivamente deformações mais acentuadas, fazendo com que as paredes de vedação trabalhem, oferecendo resistência a esses deslocamentos surgindo assim patologias que se apresentam na forma de fissuras na interface pilar/alvenaria. Desse modo, surge a necessidade de estudos das ligações empregadas na interface pilar/alvenaria, que têm por objetivo “solidarizar” estrutura e alvenaria, distribuindo as deformações excessivas da estrutura que se traduzem na forma de fissuras e com isso diminuir a ocorrência de patologias nas alvenarias de vedação. Para tal, foram desenvolvidos ensaios de diferentes formas de ligação da interface pilar/alvenaria de modo a avaliar a eficiência dos dispositivos empregados no mercado da construção de edifícios de São Paulo atualmente, como a tela metálica eletrosoldada. Numa primeira etapa foram realizados ensaios de arrancamento direto à tração, de modo a se estudar o comportamento do dispositivo quando submetido ao esforço de tração. Foram ensaiados também prismas de alvenaria, com diferentes dispositivos de ligação inseridos de modo a se avaliar as resistências à tração das ancoragens inseridas na junta de argamassa, e numa terceira etapa, foram realizados ensaios em pequenas paredes, para se determinar o desempenho das ancoragens na ligação de paredes e pilares de concreto armado, na situação real.
Structures of reinforced concrete are becoming more slender, associated to the short time of building construction and with the lesser periods of masonry fixation in the structure, each time with more frequency can be observed the formation of pathological state in masonry. The structures of reinforced concrete progressively presents more accentuated deformation, making masonry to work, offering strength to these displacements, creating pathology that appears like cracks in the interface of column/masonry. Thus, it is necessary to study the bonds used in the interface column/masonry, wich has as objective “join” the structure and the masonry, spreading the excessive deformations of the structure that comes up as cracks, and diminishing the occurrence of damages in the forbid masonry. In order to do this, different tests in the interface column/masonry were developed in order to evaluate the efficiency of device used in the civil construction in São Paulo, as tela metálica eletrosoldada. In the first step, pull-out tests were done to sutdy the behavior of the device when submitted to a tensile strength. Prisms were also tested, with different kinds of bond gadgets inserted in order to evaluate the resistance in a traction of devices in the anchorages inserted in the grouts, and in a third step, small walls were tested to analyze the behavior of anchorages in the bond of wall and column, in the real situation.

Wearable technology with optimized hardware reduces weight, increases flexibility, and could be wireless, thereby improving sensitivity, comfort, safety, and usability.In this work, flexible self-resonant coaxial transmission line resonators were investigated. Coaxial coils with multiple turns and gaps enable size optimization depending on the target application. The design was first studied in silico. Numerous prototypes were constructed and their performance was tested on the bench and in 3 and 7 T MRI. Coaxial coils were shown to be robust against bending, have no SAR penalty and improve SNR and transmit efficiency when form-fitted.A review of wireless MR, associated hardware developments and data transmission technology is given.An optical wireless communication module for sensor data transmission was demonstrated experimentally.Wearable coaxial coils offer an attractive alternative to standard coils due to low weight and flexibility. With wireless motion sensors diagnostic value in e.g. breast, knee, or cardiac MRI could be increased

Full textFrom a general perspective, AEC is one of the largest industries and surprisingly, when compared to other industries such as the automobile and airplane production, it shows one of the lowest productivity rates. One of the main solutions for increasing productivity rate is to shift the production processes from traditional to manufacturing processes. But there is a problem: Each building is a unique product and the usual manufacturing approach – Mass Production – cannot be directly adapted to the AEC industry. Thanks to new technologies, a new method has emerged: ETO or Engineered-To-Order. In this approach, the products can be fabricated corresponding to the design of the final product (building). An important challenge should be solved before: in ETO approach, the properties of the elements should be extracted from design documents. Hopefully, this problem can be solved with BIM and Artificial Intelligence. Building Information Modelling (BIM) takes advantage of powerful digital processes and new technologies in programming, such as Object-Oriented Programming languages (OOP). With BIM, it is possible to create a complete 3D model enriched by various non-graphic information of the final product. Associating BIM to Engineered-To-Order method makes the overall processes smoother and easier. In addition, there are other technologies embedded in BIM that make processes completely automatic: Parametric Design and Artificial Intelligence that led to Smart BIM Objects. By applying these technologies, designing and modelling elements can be done automatically in an optimized way. Within the current context, as the AEC industry increasingly takes advantage of intelligence adaptable digital representative of building elements. This work tries to implement AI in the work of panelling floors automatically. The research focuses on exploring how BIM capabilities and Artificial intelligence can support the production processes, in the ETO approach. To be more precise, this dissertation tries to utilize the BIM environment to make the process of panelling a floor or a wall with openings automatic. In ETO production method, it is very difficult to find a balance between the design freedom and the production limits. How is it possible to integrate the limits of production process into the design process? There are various approaches but the one used in this research, is Artificial Intelligence. The challenge is to design panels to be applied in building elements (wall, floor, and roof), considering the production rules and some restrictions. This research tries to associate the shape of elements with the production process of panels while considering the designer’s desires and the fabricator’s rules. Therefore, an algorithm was developed to create ETO panels fitted to construction elements that the designer created for the building, considering the various rules of production process. The algorithm collects the shape of element, starts to divide it to some smaller parts appropriate for panelling, modifies and finalize them for panelling. Then starts to arrange the panels and defines the size of them in an optimised way responding to production rules and limits. The algorithm developed uses the Python programming interface of Grasshopper and for the inputs and outputs, uses Tekla Structures as a BIM authoring software. This automated process not only reduces the time of work and resulting costs, but also produces more precise and optimized results. This algorithm is capable to incorporate rules that are defined by the user and calculates the result that correspond to those rules.
A AEC é uma das maiores indústrias mundiais e , em comparação com outras indústrias, como a da manufatura, apresenta uma das menores taxas de produtividade. Uma das principais soluções para aumentar a taxa de produtividade é mudar os processos de produção . Cada edifício é um produto único e a abordagem usual de manufatura - Produção em massa - não pode ser adaptada diretamente para a indústria de AEC. Graças às novas tecnologias, surgiu um novo método: o ETO ou Engineered-To-Order. Nesta abordagem, os produtos podem ser fabricados correspondendo ao projeto final do produto de construção. Um desafio importante deve ser resolvido na abordagem ETO, as propriedades dos elementos devem ser extraídas dos documentos de projeto. Este problema pode ser resolvido com BIM e com Inteligência Artificial. O Building Information Modeling (BIM) tira proveito dos poderosos processos digitais e das novas tecnologias de programação, como as linguagens de programação orientada a objetos (OOP). Com o BIM, é possível criar um modelo 3D completo e enriquecido por diversas informações não gráficas do produto final. Associar o BIM ao método Engineered-To-Order torna os processos mais fáceis. Além disso, existem outras tecnologias embutidas no BIM que tornam os processos totalmente automáticos: Design Paramétrico e Inteligência Artificial que deram origem aos Objetos BIM Inteligentes. Ao aplicar essas tecnologias, o projeto e a modelação de elementos podem ser feitos de forma automática e otimizada. No contexto atual, como a indústria de AEC aproveita cada vez mais a inteligência digital adaptável representativa de elementos de construção. Este trabalho buscou implementar IA utilizando para desenvolver a aplicação automática de painéis de parede, de pavimento e de cobertura. Esta pesquisa concentra-se em explorar como os recursos BIM e a inteligência artificial podem apoiar os processos de produção na abordagem ETO. Esta dissertação tenta utilizar o ambiente BIM para automatizar o processo de revestimento de um piso ou parede com aberturas. No método de produção ETO, é difícil encontrar o equilíbrio entre a liberdade do design e os limites de produção. Como é que se pode transferir os limites do processo de produção para o projetista? Existem várias abordagens, mas a que é escolhida nesta pesquisa é a Inteligência Artificial. O desafio consiste em projetar painéis para algum tipo de elemento de construção (parede, piso e telhado), considerando as regras e restrições da produção. Esta pesquisa tenta vincular a forma dos elementos ao processo de produção dos painéis, tendo em consideração a visão do projetista e as regras do fabricante. Para tal, foi desenvolvido um algoritmo que permite criar painéis ETO ajustados aos elementos que o projetista definiu para a edificação, incorporando as regras do processo de produção. O algoritmo inclui a forma do elemento, começando por dividi-lo em partes menores e apropriadas ao painel, as modifica e finaliza para o painel. Em seguida, começa a organizar os painéis e define o tamanho dos mesmos de forma otimizada, atendendo às regras e limites de produção. O algoritmo desenvolvido usa a interface de programação Python do Grasshopper para as entradas e saídas e usa o Tekla Structures como um software de autoria BIM. Este processo automatizado reduz o tempo de trabalho e os custos resultantes, e também produz resultados mais precisos e otimizados. O algoritmo é capaz de incorporar regras que são definidas pelo utilizador e calcular o resultado que corresponde a essas regras.

Full textThis thesis addresses canvas as a support for painting in Portugal. Concerning the area of conservation, this pictorial support is investigated from a material and technical point of view, through a set of ninety and six existing works in museums and other institutions where the Portuguese painting is well represented. Covering both religious and civil typologies, this research focuses on the evolution of the use of canvas, initially with the distemper technique, through an exemplar of late fifteenth century, and then with the oil painting technique, through paintings from late sixteenth century to late eighteenth century, when the industrial revolution promotes a new period to painting on canvas. From the technical and material point of view, the investigation focused on direct and detailed in situ observation of the reverse of paintings and involved a quantitative and qualitative analysis of the canvas. These were carried out with the support of visible light, digital photography of the front and reverse of paintings and with the use of a thread-count. The formal characteristics of the canvas were examined and micro-samples of it were collected and analysed by optical microscopy, to identify the material present. In relation to the distemper painting on canvas, the opportunity to analyse some of the constituent materials by optical microscopy, SEM-EDS and μ-FTIR, allowed to identify the raw material of the canvas, as well as some of the pigments, grounds and binder present. The approach confirmed the uniqueness of this painting, whose pictorial technique preceded the use of oil in this weaved support. For a better understanding of canvas, the traditional process of weaving in a handloom was discussed and fibres and traditional fabrics used as paintings supports were related with specific international and national artistic periods. The information gathered in this interdisciplinary approach was contextualized through coeval treatises and national and European custom of the use of canvas in the painting. It sought, with that, answer to questions about the choice of certain materials and woven structures, about cloth sizes and paintings’ dimensions, about marks and stamps on canvas over the period investigated and, therefore, relate them with preferences of local artists and also insert them in European pictorial practice. The presentation of these results allowed outlining a first idea of the distinguishing features of the canvas as fundamental elements for national painting, a subject that matters to deepen in the future, given to its influence on pictorial technique.
