Building Information Modelling (BIM) adalah sebuah pendekatan untuk desain bangunan, konstruksi, dan manajemen. Software Tekla merupakan revolusi baru dalam bidang rekayasa struktur yang memiliki beberapa keunggulan dibanding program aplikasi lainnya. Tekla Structures merupakan perangkat lunak Building Information Modelling (BIM) yang memungkinkan untuk membuat dan mengelola data secara akurat dan rinci, serta dapat membuat model struktur 3D tanpa melupakan material dan struktur yang kompleks. Penggunaan BIM di Indonesia masih hanya sebatas menjawab persoalan bagaimana mengefisiensikan kebutuhan tenaga kerja, waktu dan uang. Jika kita berkaca pada bagaimana pengaplikasian metode BIM di negara lain, potensi yang dicapai dari pengaplikasian metode BIM di Indonesia masih jauh dari kata maksimal. Tantangan selanjutnya adalah bagaimana mengenalkan teknologi aplikasi BIM ini dan mendorong penerapan BIM ini ke seluruh pihak stakeholder sektor konstruksi yang terkait. Maka dari itu, kegiatan pengabdian pada masyarakat ini bertujuan untuk memberikan pengenalan tentang Building Information Modelling dan memberikan keterampilan dasar dalam penggunaan aplikasi teknologi BIM dengan software Tekla Structures. Kegiatan ini dilaksanakan di Departemen Teknik Sipil, Universitas Hasanuddin yang dihadiri oleh 35 peserta yang berasal dari kalangan praktisi dan akademisi. Tahapan kegiatan pengabdian meliputi kegiatan sosialiasi ke stakeholder melalui mitra Lembaga Pengembangan Jasa Konstruksi Provinsi Sulawesi Selatan (LPJKP Sul-Sel), pengumpulan data berupa shop drawing, pembuatan modul, pemodelan dan laporan berupa quantity dan gambar kerja.

The purpose of this study is to enhance productivity and economic value with precise object information generation and reinforcement quantity take-off by developing the Automation Reinforcement Placement System of Foundation (ARPF). This study was conducted by selecting the most basic form, spread footing, and no force was applied on the foundation other than axial force. For the development of ARPF, variables that should be input into the typical programs directly by users were minimized through developing the reinforcement placement algorithm by using visual C# based on the reinforced concrete structure design standard. The process of reinforcement detail placement formation was performed in the Tekla Structure (TS) that has outstanding accessibility and usability of API. Objects made by applying ARPF enable information confirmation and modification, as typical ones. Through this process using ARPF, rapid and precise reinforcement quantity take-off and footing bar placement are possible. If modeling is performed on the Tekla Structures by using ARPF, a detailed 3D reinforcement placing drawing, not 2D, can be created. It is expected that this method may take a smaller amount of time and effort than the typical drawing generation method that users had to generate objects or input information themselves.

Innovations in the construction industry have led to a change in the technological structure, the use of end-to-end technologies, innovative materials, information management and the need for new technical, technological and managerial solutions. The research problem is the optimal placement of glass-fiber reinforced plastic bars in concrete structures. It took several steps to solve the research problem: 1) development of an algorithm for solving the design problem in TEKLA Structures; 2) performing of calculations based on the finite element method in LIRA-SAPR, which were further reproduced in Rhinoceros and Grasshopper (based on interoperability in a single BIM environment); 3) implementation of the optimization algorithm using the parametric optimization method; 4) A practical calculation of determining the optimal values of the loads of glass-fiber reinforcement in the slab on the example of a typical design problem of a structural element of a construction facility; 5) calculation of positive economic effect. The conclusion is that the algorithm can be used in the practice of building design.

Full textAbstract:
The paper describes the verification of the quality of the data transfer between selected software dedicated to generation of building models and for their analysis using the finite element method. For comparison, models of two typical structures are constructed: a steel truss hall and a multi-storey reinforced concrete building. Both models are created simultaneously in two programs: Autodesk Revit and Tekla Structures. Next, these models are exported to computational packages: Autodesk Robot, Dlubal RFEM and SCIA Engineer. Different options of data transfer are considered, in particular: a direct link between programs as well as via open formats. The scope and limitations of the data exchange are determined in each case. Juxtaposition of the effectiveness of different transfer methods for such typical building models are helpful at the stage of cooperation between the architect and the structural designer. In addition, pilot results of a finite element static analysis for the steel hall model are also compared.

Full textAbstract:
I detta examensarbete studeras programvarorna Tekla Structures och Revit Structures djupgående under projekteringsfasen. En fallstudie ligger till grund för att jämföra programvarorna, med syfte att hjälpa byggkonstruktörer i valet mellan respektive programvara. Examensarbetet är utfört i samarbete med Kåver & Mellin Uppsala och jämförelsen ska hjälpa företaget att besluta om det finns skäl att utbilda sina medarbetare inom Tekla. Fallstudien har byggt på ett referensprojekt som utfördes i respektive programvara. Referensprojektet bestod av vanligt förekommande konstruktionselement och utförandet delades upp i två huvudområden, modellering och ritningsframställning. Modelleringen avser de moment som krävs för att skapa en 3D-modell över byggnaden medan ritningsframställning avser de moment som krävs för att framställa kompletta ritningar över byggnaden. Under utförandet upprättades fyra ritningar i respektive programvara, ritningarna utformades efter standarden Bygghandlingar 90. En viktig faktor för utförandet av fallstudien visade sig vara den rådande kunskapsnivån hos användaren i respektive programvara. Detta speglades i resultatet för tidsåtgången. Eftersom författarna hade större förkunskaper i Revit kunde många av momenten utföras snabbare än för Tekla. Att åstadkomma en rättvis jämförelse mellan programvarorna i tidsåtgång blev följaktligen svår men fallstudien hjälpte författarna att kunna dra slutsatser kopplade till programvarornas styrkor och svagheter samt användarvänlighet. Tekla hade stora styrkor inom stålprojektering och programvarans förmåga att upprätta tillverkningsritningar på ett effektivt var av stor betydelse. Men programmet visade svagheter i ritningsframställningen där verktygen var otillräckliga för att kunna färdigställa referensprojektets detaljritning med korrekt skraffering. För Revit var det just programvarans detaljeringsverktyg i ritningsframställningen som var den stora styrkan. Programvaran hade verktyg för att rita ut alla ingående delar som skulle ingå på detaljritningen. För stålprojektering saknade programvaran verktyg för att effektivt kunna modellera upp alla ingående delar av en stålpelare, och stora delar av projektering för stål fick utföras under ritningsframställningen med hjälp av 2D-grafik. För företaget Kåver & Mellin Uppsala rekommenderas det att utbilda sina medarbetare i Tekla om de avser att ta sig an projekt med omfattande stålprojektering.

Full textAbstract:
Kostnaderna för att bygga idag är höga och det krävs att byggbranschen effektiviseras för att sänka dessa. I takt med sökandet efter ständig effektivisering har verktygen utvecklats. Inom konstruktion har man på 25 år gått från att rita med penna och papper, till att bygga upp en tredimensionell modell i en dator. Idag ritar de flesta dock fortfarande i två dimensioner med programmet Autodesk Architectural Desktop, ADT, ett AutoCAD baserat program från Autodesk. Nu finns program som är objektbaserade, dessa bygger upp byggnaden i dess tredimensionella geometri. Programmet plockar sedan ut 2D-ritiningar ur modellen och information om olika komponenter littereras. Ett exempel på ett sådant program är Teklam Structures. Vilka effekter och skillnader i tidsåtgång som finns i användandet mellan de olika programmen kommer att åskådliggöras i denna rapport. Tekla Structures är ett program för konstruktionsritningar och lämpar sig mycket bra till byggnader med stål- och betongstomme. Eftersom de flesta inom projektering arbetar med DWG-filer underlättar det om alla kan arbeta efter samma modell, då är ADT ett bra alteranativ. En stor fördel för Tekla Structures är att ur den modell som skapats finns all information som behövs för projektering, tillverkning och montering. Ritningarna som genereras är alltid uppdaterade och aktuella.<br>The 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 textAbstract:
Byggbranschen är inne i en övergångsfas mellan 2D och 3D. BIM, som arbetsmetod, och 3D-modeller blir allt vanligare. I broprojekt är dock efterfrågan på dessa modeller låg. På WSP i Stockholm används 3D-modelleringprogrammet Tekla Structures i stor utsträckning på flera avdelningar. Önskemål finns om att utöka användningen av programmet även inom broprojektering. För att det ska bli möjligt krävs en större efterfrågan hos företagets kunder. Detta examensarbete har till syfte att ur kundens synvinkel utvärdera Tekla Structures som verktyg samt vilken nytta kunden har av Tekla-modeller. För att kunna belysa ämnet ur detta perspektiv har intervjuer gjorts med olika kunder till WSP. Deras behov och syn på BIM och Tekla Structures i brosammanhang har kartlagts och analyserats. Aspekter som kunden lyft fram i intervjuerna har fungerat som plattform för analys av en 3D-modell som konstruerats med hjälp av Tekla Structures samt två redan projekterade broar, modellerade i samma program. Analysen visar att kundnyttan av att använda Tekla-modeller i broprojekt är stor men för att möjliggöra hantering av modellerna krävs stora insatser. Utvärdering av programvaran visar även dess starka respektive svaga sidor. Resultatet av arbetet redovisas i rapportens följande sidor.<br>The 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.

This project is the result of a cooperation between HalmstadUniversity and EABAB. The aim of the project was to create a macro that would help EABAB automate the process of designing steel trusses. When run in Microsoft Excel, the macro imports and processes coordinates from a calculator program. The data is then imported into the Building Information Modelling software Tekla Structures, which creates a 3D structural model of the steel truss. The macro saves much time in the project planning process and also helps minimize the risk of design flaws caused by human error.

Full textAbstract:
Idag tillämpas BIM (Building Information Modeling) som ett ledande verktyg inom byggprojektering och möjliggör lösningar som är hållbara och optimerade mellan olika discipliner för att effektivt hantera informationsflöden. Vid överföring av data mellan programvaror används ett neutralt filformat, IFC (Industry Foundation Classes). Detta filformat exporteras från 3Dmodelleringsprogrammet Tekla Structures. Syftet med detta examensarbete är att granska orsaken till saknad information vid IFC-export från Tekla Structures. Studien innefattar en fallstudie, komparativ studie samt intervjuer. I fallstudien studeras inställningarna för en IFC-export från en komplex modell i Tekla Structures. Den komparativa studien berör två samordningsprogram Solibri Model Checker och Navisworks Manage, som sedan ställs mot varandra. Det som undersöks är hur IFC-filer lämpar sig i samordningsprogrammen. Intervjuerna har legat till grund och har gett tydliga riktlinjer under arbetets gång. Resultatet av denna studie tyder på att orsakerna kring saknad information i IFC-filer är den mänskliga faktorn och bristande kunskaper av inställningarna i en IFC-export. Ytterligare resultat är jämförelsen mellan samordningsprogrammen som visar att båda är lämpade för IFC-formatet. Genom den komparativa studien har det visat att Solibri lämpar sig bättre för IFC-exporter från Tekla Structures. Med hänsyn till examensarbetets resultat är den mänskliga faktorn avgörande för informationsförluster. Den mänskliga faktorn utgör att det råder bristande kommunikation samt bristande kunskap om IFC-exporter.<br>Today, 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 textAbstract:
Vid uppritandet av byggmodeller på WSP Group i Norrköping använder man idag två program: TEKLA Structures och AutoCAD Architecture. En av anledningarna till detta är att armeringsverktyget Impact Reinforcement i AutoCAD Architecture fungerar bättre än armeringsverktygen i TEKLA Structures. Då man behöver armering i en TEKLA Structures modell exporteras denna till AutoCAD Architecture där armeringsjärnen sedan ritas in. Jag har därför undersökt skillnaderna mellan de båda programmens armeringsverktyg, resultatet är att Impact Reinforcement är lättare att använda medan TEKLA Structures tar längre tid att lära sig, men skulle kunna göra arbetet effektivare med rätt kunskaper.<br>When 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 textAbstract:
Digitaliseringen ger möjligheter till nya och effektivare arbetssätt inom alla möjliga branscher. Nya programvaror och tilläggsfunktioner släpps allteftersom och det finns mycket ny information att ta in för de personer som anpassar sig till dessa nya programvaror. Även fast dessa digitala lösningar har fördelar ur både kostnads- och ekonomisynpunkt kan det vara besvärligt att ändra sitt arbetssätt och implementera nya vanor på arbetsplatsen. Tekla Structures är ett BIM-verktyg (byggnadsinformationsmodellering) ägt av Trimble som används flitigt inom byggbranschen. Syftet med detta arbete är att utforska och sammanställa möjligheterna kring Trimbles nysläppta verktyg Tekla Bridge Creator vid broprojektering. I dag kan Tekla Structures användas tillsammans med Rhinoceros och dess tilläggsfunktion Grasshopper genom Grasshopper-Tekla Live Link men arbetsgången kan anses krånglig och kräver bra kännedom i programmet. Rapporten beskriver utformningen av en bromodell i Bridge Creator och sedan en likadan i Grasshopper. Därefter jämförs arbetssättet för att slutligen ge förståelse för Bridge Creator och en uppfattning för hur den bäst kan nyttjas vid broprojektering samt om den kan vara av nytta för den specifika personen med det målet denne har. Bridge Creator har visat sig ha många begränsningar vad gäller utformning av parametriskt anpassningsbara bromodeller, vilket möjliggörs i Grasshopper. Kortfattat innebär det att kunna välja ut specifika parametrar som exempelvis brons totala längd och bredd och att hela modellen snabbt anpassas när dessa ändras. Om exempelvis brons totala längd ändras måste upplag, räcken och liknande byggnadsdelars position ändras manuellt. I Grasshopper kan dessa byggnadsdelar anpassas så att om brons längd ändras följer upplag och räcken med vid längdändringen. Det är svårt att avgöra om Bridge Creator är att rekommendera eller inte, det är helt beroende på användarens tidigare kunskapsnivåer, vilka brokonstruktioner som skapas, hur anpassningsbara de ska vara samt hur stort värde som ligger i att kunna återanvända i nya projekt. Bridge Creator är dessutom i en utvecklingsfas och genomgår förbättringar allt eftersom vilket innebär att det inte går att utesluta att det i framtiden kan användas likt Grasshopper för att skapa parametriskt anpassningsbara bromodeller.<br>Digitalization gives opportunities to new and more efficient workflows within all different type of industries.

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 textAbstract:
Utvecklingen av BIM har senaste åren tagit fart och många länder, inklusive Sverige har bland annat påbörjat en process mot gemensam struktur inom byggsektorn genom att standardisera informationshantering och processer (Nilsson, 2013). Denna utveckling innebär nya möjligheter för aktörerna i byggprocessen men också problematik då denna intensiva IT-utveckling möter en till synes konservativ bransch (Statskontoret, 2009:6). Syftet med föreliggande examensarbete är att utforma en moderniserad arbetsmetod för konstruktören som integrerar dennes BIM-verktyg i projekteringsprocessen. En förståelse för hur konstruktörens arbete ser ut idag skall utrönas, samt vilka möjligheter och svårigheter som denna aktör upplever. Det som framkom i studien var att trots den intensiva utvecklingen av BIM som varit de senaste åren tillämpas fortfarande traditionella processer, då förståelse för en mer omfattande inledande arbetsinsats ännu inte riktigt finns. Ökade krav ställs också på konstruktörens byggtekniska kompetens då det är svårare att “fuska” i objektbaserade modeller. Den kvalitativa studien påvisade ett konservativt synsätt där utvecklingen av konstruktörens roll med hjälp av exempelvis färdiga komponenter från olika leverantörer i Tekla Structures sågs snarare som problematisk än fördelaktig. Det framkom även att vikten bör ligga på samordning i projekten, där mer än krocktester borde tas i beaktning och att granskning borde ske i ett tidigare skede samt utföras mer kontinuerligt. I den praktiska tillämpningen av Tekla Structures upptäcktes också flera möjligheter till granskning och samordning av ett projekt. Det behov av standardiserad BIM som konkretiserades i teoriavsnittet bekräftades också av respondenterna i form av önskan om en gemensam struktur i modellerna. Examensarbetet resulterade i en arbetsmodell för hur konstruktören bör arbeta vid BIM-projektering och vilka förutsättningar som efterfrågas för att möjliggöra detta arbetssätt. En viktig del i detta är att definiera ett väl strukturerat och tydligt arbetssätt som uppnås genom klara mål. Centralt för varje BIM-projekt är att utse en BIM-samordnare var uppgift är att följa upp arbetet mot de satta målen och säkerställer en enhetlig projektering bland projektörerna. BIM erfordrar en helhetsförståelse vid projektering för att tillgodose de nya krav som ställs.<br>The 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 textAbstract:
I detta examensarbete har en studie utförts för att ta fram och jämföra metoder att modellera krökta vangstycken av stål med komplexa geometrier i programmet Tekla Structures. Avgränsningen för studien har varit att jämföra två metoder: Metod 1 använder verktygen Complex Polybeam Creation i kombination med Surface Generation Between Polybeams i Tekla, och Metod 2 trappverktyget Spiral Staircase. En vindeltrappa från projektet Patienten och Princeton, Sankt Eriks ögonsjukhus i Hagastaden, har använts för att testa de komplexa geometrier som denna vindeltrappa medför. Utifrån detta har Tutorials av de båda metoderna skapats, för att läsaren enkelt ska kunna följa och genomföra samma steg. Resultatet av examensarbetet är att båda metoderna fungerar för modellering, beroende på vilken typ av geometri som skapas. Efter modellering med trappverktyget Spiral Staircase gick det inte att ta fram korrekta tillverkningsritningar av de horisontella plåtarna, till skillnad från Metod 1. Slutsatsen av studien är att vid enbart snabb modellering av cirkulära geometrier samt framtagning av tillverkningsritningar för vertikala krökta plåtar, kan med fördel Metod 2 användas. Däremot vid framtagning av tillverkningsritningar av komplexa och icke cirkulära geometrier lämpar sig Metod 1 bäst.<br>In 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 textAbstract:
The Teacher Education Collaborative in Language Diversity and Arts Integration (TECLA) initiative prepares elementary teachers at a Southwest majority-minority university. TECLA emerged from a social justice commitment to prepare teachers to work in linguistically and culturally diverse schools. The program integrates interdisciplinary arts-based approaches and culturally sustaining language acquisition strategies throughout the teacher education experience. TECLA conceptualizes social justice through a sociohistorical lens. Social justice is experienced when all people have equitable access to meaningful opportunities to participate in and (re)shape the social structures in which they live and work. TECLA relies on an expanded definition of social justice that includes building on students' home cultures, languages, and experiences to design rigorous educational experiences.

Full textAbstract:
In this paper, 3D numerical simulations are performed to investigate the mixing process within an improved Tesla micromixer. This improved Tesla micromixer applies the flow separation/recombination and converging/diverging principles to enhance mixing. A portion of the working fluid, which separates from the main flow, enters the Tesla side branch and mixes with the main flow again at the exit of the Tesla unit. The tested volume flow rate ranges from 1 μL/min to 100 μL/min. Grid independence is carried out to minimize the effect of numerical diffusion. Optimization is done to determine three parameters, which are the gap ratio (H/W), the mixing cell number (N), and the angle at the gap inlet (β). The effects of these three parameters on mixing are investigated at a volume flow rate of 100 μL/min. The simulation results show that the gap ratio is the most important factor. Three parameters are selected as H/W = 50/200, N = 10 and β = 90° for further investigation. The traditional Tesla micromixer is also simulated for comparison with the present design. The mixing efficiency is approximately 60% in the range of the tested volume flow rate. The improved micromixer has better mixing efficiency than the traditional Tesla micromixer when the volume flow rate is less than 50 μL/min.

In this study, a parametric investigation on mixing of two fluids in a modified Tesla microchannel, has been preformed. Modified Tesla micromixer applies both flow separation and vortices string principles to enhance the mixing. The fluid stream splits into two sub-streams and one of them mixes with the other again at the exit of the Tesla unit. Analyses of mixing and flow field have been carried out for a wide range of Reynolds number from 0.05 to 40. Mixing performance and pressure drop characteristics with two geometrical parameters, i.e, ratio of the diffuser gap to channel width (h/w) and ratio of the curved gap to the channel width (s/w), have been analyzed at six different Reynolds numbers. The vortical structure of the flow has been analyzed to explain mixing performance. The sensitivity analysis reveals that mixing is more sensitive s/w, than the h/w.

With consideration of the good configuration of Tesla tube and its perfect performance used in micromixer and micropump, an integration of micromixer and micropump, a novel type of piezoelectric micromixer has been designed. In order to improve the performance of the micromixer, analysis on structure parameters of the Tesla tube, and the optimization on it is the chief work in this paper. Firstly, a novel type of piezoelectric micromixer with Tesla tubes and piezoelectric actuator has been designed, and its structure and working principle were described. Secondly, the numerical analysis on the micromixer with prearranged parameters was carried out to analyze its pumping and mixing performances. Thirdly, an optimization on the structure to improve its performance was carried out. The values of three main structure parameters of the Tesla tube, K = W1/W3, L1 and L2 were changed to analyze their effects on λ and σ which stand for pumping and mixing performances respectively, then two groups perfect values of those three parameters were selected for optimization. Finally, a perfect design scheme was selected to be structure of mixer; numerical analysis was carried out on it in application of dynamic mesh model. Two fluids arrived perfect mixing after 0.4s with the value of Reynolds number 200, at driven frequency 100Hz, middle displacement amplitude of piezoelectric actuator 15μm. This result demonstrates that, pumping and mixing performances of the piezoelectric micromixer were validated, and its working performance has been improved with the optimization on Tesla tubes, which can be reference for study afterward.

Full textAbstract:
The Tesla valve is a passive-type check valve used for flow control/rectification in a variety of micro/mini-channel systems. Previous studies have focused on its optimal design and effectiveness (i.e. diodicity) for the low-Reynolds number regime (Re < 500). Using three-dimensional (3D) CFD, multiple, identically-shaped Tesla valves arranged in-series, i.e.: a Tesla “tree” or multi-staged Tesla valve (MSTV), were investigated. Fully-developed flow at the inlet and complete-laminar conditions throughout the entire valve structure were imposed on all numerical simulations. The number of Tesla valves, valve-to-valve distance and Reynolds number were varied to determine their effect on MSTV diodicity. The individual Tesla valves within each MSTV possessed pre-optimized design parameters as reported from the literature. Results clearly indicate that the MSTV can provide for a significantly higher diodicity than a single Tesla valve and that this MSTV diodicity increases with Reynolds number. Minimizing the distance between adjacent Tesla valves can significantly increase the MSTV diodicity and, for very low Reynolds number (Re < 50), the MSTV diodicity is near-independent of valve-to-valve distance and number of valves used. In general, more Tesla valves are required to maximize the MSTV diodicity as the Reynolds number increases. The current investigation also demonstrates that 3D numerical simulations more accurately predict the diodicity of a single Tesla valve over a wider range of Reynolds numbers.

Full textAbstract:
A Tesla valve is a fluidic dioide that may be used in a variety of mini/micro channel applications for passive flow rectification and/or control. The valve’s effectiveness is quantified by the diodicity, which is primarily governed by the incoming flow speed, its design and direction-dependent minor losses throughout its structure during forward and reverse flows. It has been previously shown that the Reynolds number at the valve inlet is not representative of the entire flow regime throughout the Tesla structure. Therefore, pure-laminar solving methods are not necessarily accurate. Local flow instabilities exist and exhibit both transitional and turbulent characteristics. Therefore, the current investigation seeks to identify a suitable RANS-based flow modeling approach to predict Tesla valve diodicity via three-dimensional (3D) computational fluid dynamics (CFD) for inlet Reynolds numbers up to Re = 2,000. Using ANSYS FLUENT (v. 14), a variety of models were employed, including: the Realizable k-ε, k-kL-ω and SST k-ω models. All numerical simulations were validated against available experimental data obtained from an identically-shaped Tesla valve structure. It was found that the k-ε model drastically under-predicts experimental data for the entire range of Reynolds numbers investigated and cannot accurately model the Tesla valve flow. The k-kL-ω and SST k-ω models approach the experimentally-measured diodicity better than regular 2D CFD. The k-kL-ω demonstrates exceptional agreement with experimental data for Reynolds numbers up to approximately 1,500. However, both the k-kL-ω and k-ω SST models over-predict experimental data for Re = 2,000.

Full textAbstract:
A novel fabrication process is presented to create ultra thick ferromagnetic structures in silicon. The structures are fabricated by electroforming NiFe into silicon templates patterned with deep reactive ion etching (DRIE). Thin films are deposited into photoresist molds for characterization of an electroplating cell. Results show that electroplated films with a saturation magnetization above 1.6 tesla and compositions of approximately 50/50 NiFe can be obtained through agitation of the electrolyte. Scanning electron microscopy (SEM) images show that NiFe structures embedded in a 500 μm thick silicon wafer are realized and the roughening of the mold sidewalls during the DRIE aids in adhesion of the NiFe to the silicon.

Full textAbstract:
In this paper, the influence of an external magnetic field on the vibration responses and damping ratios of a vascular beam filled with three different magnetic nanofluids are investigated. First, the equation of motion of a fluid-filled beam is derived based on the published works and some amendments are made to simultaneously include the damping ensuing from the surrounding air and also the effects of viscosity of the fluid inside the vascular channel. Then, the effects of an external magnetic field on the viscosity of the fluid is studied and incorporated into the equation of motion of the beam. Finally, based on three magnetic nanofluid samples, simulations are conducted to represent the changes in frequency response functions and damping ratios of the vascular channel beam. The maximum increase observed in the viscosity of the magnetic nanofluid samples under the influence of magnetic field with the intensity of 1 Tesla was 16%, while the reduction in the vibration amplitude found 12.7% and 33.8% for the first and second vibration mode under the influence of the maximum magnetic field intensity of 0.3 Tesla. Moreover, the maximum decrement of the damping ratio was 1.1% under the same magnetic field. However, it seems that the higher values for vibration reduction can be achieved by using the magnetic nanofluid with higher magnetic particle concentrations and viscosities.
