Modern intensive development of precast-cast-in-place construction has led to creation of a wide range of various constructive systems of buildings during the last 100 years. They allow constructing buildings with best account of the requirements of functionality, architectural expressiveness, production possibilities of construction companies, etc. However in spite of this development both precast and cast-in-place housing construction has its peculiarities, positive and negative ones. The constructive systems of precast monolithic buildings existing at the moment are based on the required mutual deformation of prefabricated reinforced and cast iron reinforced concrete at the stage of a building construction and at the stage of its use as well. Having refused from this rule, the authors of this article have introduced a constructive system of a precast monolithic building able to bear loads, developing at the stage of erection (due to completion of a precast frame) and at the stage of use (due to completion of a precast monolithic frame). The offered construction of a precast monolithic building frame allows efficiently using the advantages of precast and cast-in-place construction minimizing their disadvantages and it also fully corresponds to the obligatory requirements to buildings. The corresponding patents are obtained.

The Precast/Prestressed Concrete Institute (PCI) sent an assessment team to Chile, which visited the areas affected by the 27 February 2010 earthquake between 26 and 30 April 2010. This paper reports on the team's observations on the performance of precast/prestressed concrete structures. The precast concrete building systems observed by the PCI team generally performed well. In some cases, the lateral force-resisting system performed satisfactorily, but the absence or weakness of diaphragm framing resulted in local failures. Overall, the PCI team found a mature and sophisticated precast concrete industry that has successfully considered and solved issues of earthquake resistance without some of the constraints imposed on U.S. practice by restrictive building code provisions.

Multi-storey building would be the greater part influenced by quake constrains to seismic prone areas. The major concern in the design of the multi-Storey building is the structure to have enough lateral stability to resist lateral forces buckling to control lateral drift and displacement of the building. The application of the shear wall system in Reinforcement concrete (RC) building has been widely used to minimize seismic consequences. Besides, the building with concentrated steel bracing system is used for the building. Both of the system has significance of the structural performance. Although both systems are used for same reason, their effect shows unequal variation and behaviours against seismic load. In the Project, G+10 storey building, along with shear wall and bracing are being considered for the analysis. The performance of building will be evaluated on the basis of following parameters Story displacement, Storey drift. In this work, the shear wall and bracing are provided at different locations with the overall analysis to be carried out using STAAD PRO Reinforced concrete structures are in greater demands in construction because the construction becomes quite convenient and economical in nature. RCC construction is best suited for low rise building but in High rise building construction are composite is a better option among the RCC and steel Structure.

Purpose The purpose of this study is to identify existing weaknesses in precast concrete building maintenance and how to overcome it. The contemporary practice of conventional methods in the pre-cast concrete (PC) building maintenance entails many issues such as PC component aesthetic and structural defects, no integration between maintenance systems and lack the intelligent capabilities of linking defect diagnosis operations in maintenance due to poor service delivery and defect repetition. A key problem impeding the widespread adoption of emerging technologies is the lack of competent contractor supporting the effectiveness of implemented information and communication technology than conventional methods and the returns on investment. Design/methodology/approach The shortcomings of conventional methods are assessed from the perspective of PC buildings. Several data were collected through a case study of eight PC buildings from high-rise and complex buildings. Findings The conventional methods had significantly little emphasis on defect diagnosis tools. It had also increased the inadequate strategic decision making to analyse information in improving the maintenance project outcomes for PC building. Originality/value Building information modelling tools is suggested from findings and lessons learned as a good practice to reduce the repetition of defects on the design specification used and construction practiced.

Introduction. The partial replacement of cast-in-situ concrete with precast concrete in the residential construction sector allows to reduce construction time and cost, increase labour productivity and cut CO2 emissions. Combinations of prefabricated and monolithic elements in precast monolithic frames are presented; they encompass 6 different structural options of precast monolithic frames and 2 types of monolithic frames. The co-authors compare production costs and integrated labor intensity for all frame design options, construction periods per 1,000 m3 of a residential building for various structural options of the frame, and assess potential reduction in carbon dioxide emissions due to a change in the amount of precast reinforced concrete in the building frame structure.
 Materials and methods. The co-authors have developed a method that employs weighted average to identify the optimal type of a precast monolithic frame. The method takes account of such factors as production costs, integrated labour intensity, construction time and reduction in carbon dioxide gas emissions (in per centum) per 1,000 m3 of the frame structure.
 Results. The optimal structure of a precast monolithic frame was selected and calculated using weighted average. Weighted average was used to identify the most effective structural frame. The calculation results have shown that ARKOS precast monolithic frame with precast columns is the leader in terms of weighted average; it best suits the construction of a residential building. If we consider each of the selected indicators separately, RECON frame with precast floors is to be selected; however, RECON is inferior to ARKOS in terms of weighted average due to different values of the weight coefficients attached to each of the assessment criteria.
 Conclusions. The co-authors have proven the efficiency of precast monolithic frame systems in comparison with monolithic frames if applied to construct a residential building. The proposed method was employed to select the optimal type of frame.

This paper aims to study the progressive collapse of the PSRC building using non-linear dynamic analysis and U.S. General Service Administration (GSA) guidelines during extreme loading. Two structures are studied to validate the performance of progressive collapse of PSRC and RCC structures. Four-story PSRC and RCC buildings are designed according to Indian Codes of practice.

Precast concrete technology is recognized worldwide as offering significant advantages. Despite the advantages they offer, precast concrete building systems’ share in both Turkey and the U.S. is very low, especially when compared to many European countries. Since Turkey is a developing country that is technologically dependent on the developed world, low share of industrialized building systems is highly expected in that country. However, the U.S. is a developed and industrialized country, so it was very interesting to see that these systems are not extensively used in that country either. This study investigated the factors that prevent the extensive use of precast concrete systems in the U.S. and Turkey through an extensive questionnaire survey. The survey results revealed that the perceptions of the American vs. Turkish respondents on most of the factors that affect the use of precast concrete systems are significantly different from each other. While American respondents considered size and load restrictions on transportation, poor communication among parties, and lack of qualified contractors specialized in precast concrete systems as three most important barriers to the extensive use of precast concrete systems in the U.S. building construction market, Turkish respondents ranked lack of good communication among parties and lack of structural engineers and contractors specialized in precast concrete systems as the most important three factors that prevent the extensive use of these systems in Turkey. This study indicated that precast concrete users and manufacturers should recognize that the main reasons for low utilization of precast concrete systems predominantly depend on the prevailing conditions of the country in question.

Abstract In the implementation of building construction, especially in the context of functionality of campus buildings, punctuality is an important thing that must be strictly followed because it concerns the start of lecture schedules that cannot be delayed. Therefore, it is necessary to have precise time management of building construction during all the implementation. It’s cannot be separated in building construction between the innovation of work methods and improvisation of quality control which are two processes that need to be implementation in an effort to achieve efficiency and. One of the innovations in building construction, is installation of a concrete precast wall as a cover for the facade of the Binus campus building. Concrete precast wall is made of a good material, as an effort to reduce solar heat entering the room. Furthermore, all existing constraints must be mapped properly as support implementation concrete precast wall. One of antecedents of implementation concrete precast wall in building construction is time management of machine construction tools when use tower crane. Researcher knows the issues of building construction are limitations time using tower crane efficiently, working tools, weather conditions, time of material application, labelling system, quality control mechanism and installation system. In other side, those strengths, weaknesses, opportunities, threats, that can be used as an approach and analysis, start from resource mapping, work requirements, material quality control and coordination systems between sub-supporters. The success of this work depends on the application and coordination calculation time, inspection and quality procedure is main of a consistent methodology from manufacturing in the workshop to installation in the field. In addition, efficiency and effectiveness can provide good quality, saving time and costs.

In the context of Industrialised Building Systems (IBS), precast concrete buildings are composed of multiple structural members that are interconnected through different techniques. The adoption of precast concrete wall panels has gained significant traction in contemporary construction methodologies. Nevertheless, the utilization of dapped connections specifically designed for non-load bearing applications in precast walls incorporating recycled concrete aggregate (RCA) remains largely unexplored and limited in practice. This research proposes a new wall-to-wall connection for precast wall panels to enhance the constructability of IBS for non-load bearing walls. The novel Cross Dapped (CD) design enables horizontal panel installation in confined areas with existing structural frames, while ensuring the connection’s strength as a non-load bearing wall to prevent failure. Uniformly distributed loads are applied until sample failure, recording compressive load patterns, deflection, stress-strain patterns, and crack patterns on the wall surface. The CD connection demonstrates applicability for precast wall-towall connections, improving IBS constructability with its innovative design and locking system. Overall, this research explores and proposes an efficient and structurally sound wall-to-wall connection design for precast wall panels of non-load bearing system, facilitating the adoption of IBS methods, and improving the overall quality and constructability of building systems.

The article discusses technologies for constructing energy-efficient, earthquake-resistant buildings that have increased rigidity and strength in their main components. These technologies utilize structures with enhanced damping and active seismic insulation systems. Practical implementations, design features, and technological aspects are examined. An analysis is conducted on the characteristics of current technologies, the conditions for production and installation, repairability, and their impact on the building's energy efficiency during operation. Technologies are systematized and categorized based on their principles of seismic protection during the analysis process. The analysis was conducted based on the following main criteria: steel consumption, suitability of repairable technologies used, possibility of implementing seismic protection during building reconstruction, ability to withstand seismic effects, feasibility of implementation, and energy efficiency. It has been determined that traditional technical solutions to increase rigidity and strength, such as introducing structures with increased damping used for buildings with precast, monolithic, and precast-monolithic frames, require a significant amount of additional resources. These solutions are characterized by accumulation of failures in individual hidden elements due to seismic loads, low maintainability, and often decrease the energy efficiency of the building. The use of seismic energy-absorbing mechanisms with high efficiency can significantly reduce resource costs for construction and increase maintainability, thus improving the overall sustainability of the structure. Based on the findings of the analysis, the following recommendations are made for conducting further studies on active protection systems in terms of design, development of construction technology, and potential application in the renovation of existing buildings.

Due to the increasing types of special impacts on buildings and structures, which often have a dynamic nature, there is a need to improve structural systems to ensure protection against such impacts. Reducing the weight of load-bearing structures of building frames and increasing the static indeterminacy of structural systems are among the effective methods of protection not only under seismic conditions but also during special and emergency impacts. As part of addressing this issue, the article proposes a new rapidly erectable structural system for residential and public buildings, made from industrialized panel-frame elements in a precast-monolithic configuration. In this system, the building frame is assembled from precast reinforced concrete structures of two types: panel-frames in the form of inverted U-shaped elements and L-shaped industrially manufactured elements. The connection of these structures on the construction site into the building frame, within the plane of the panel-frames, is carried out using two types of platform joints and monolithic embedding of the upper parts of the precast panel-frame elements’ beams together with multi-void slabs. In the orthogonal plane of the panel-frames, the frame is formed by monolithic tie beams and multi-void floor slabs. The conducted assessment of the mechanical safety of the proposed structural system demonstrated its high resistance to progressive collapse under special impacts. A comparative analysis of technical and economic indicators, such as material consumption, cost, and transportation expenses, revealed significant advantages over buildings constructed using traditional panel systems.

Abstract Concrete buildings with modular systems are still not widely used for high-rise buildings. One of the main reasons is the lack of knowledge regarding the structural design of concrete modular buildings. In Indonesia itself, there are not even many concrete modular buildings because the majority of the area is surrounded by earthquake zones. This study aims to develop a frame analysis method using a section designer for structural analysis of concrete modular buildings. The function of using frame elements is to simplify the calculations that should be modelled with shell elements in order to ensure that the connection between segments occurred only vertically. The analysis was carried out for an 8-storey apartment modular building composed of 4 module segments (M-24A, M-24B, M-36A and M-36B). Seismic analysis was carried out using the parameters of the city of Kutai with Sds = 0.27 and Sd1 = 0.3. All module segments are capable of enduring the maximum moment caused by seismic loading. The M-36B segment has a maximum moment capacity of 62,318.73 kNm and can withstand an ultimate moment of 2,227.55 kNm. The combined effect of the earthquake due to the response spectrum created maximum building story drift of 0.11% does not exceed the required limit of 2%.

Problem. A large number of construction objects in Ukraine have been damaged or completely destroyed as a result of hostilities that have been ongoing since 24 February 2022. There is an urgent need for rapid reconstruction of the housing sector and infrastructure facilities. Building with precast structures is a way to minimize the time of work, but it is not as reliable as building with cast-in-place structures. The middle ground is the technology of building with precast and cast-in-place structures, which provides the necessary speed and reliability. However, such technology is not often used in Ukraine currently. This is explained by a significant decrease in precast concrete plants and insufficient research on precast and cast-in-place solutions. Therefore, the prospects of the technology of building with precast and cast-in-place structures for the restoration of construction objects are being investigated. Methods. An analysis of publications, a comparison of various technologies, and a review of the practical experience of building a low-rise object with precast and cast-in-place structures in Kharkiv have been carried out. Results. The technology of building with precast and cast-in-place structures is a way to save 10 to 40% of materials compared to other construction systems, reduce unskilled work to a minimum, simplify the quality control process, reduce the share of welded joints, optimize the involvement of highly qualified workers, and maximally mechanize all stages of construction; reduce electricity consumption; minimize the time, reduce the cost of construction by 10 to 30% compared to the existing technologies.Originality. The proposed concept of versatile adaptive designs of building with precast and cast-in-place structures as in the case of a new neighbourhood, which will include a school, a kindergarten, an administrative building, residential buildings with commercial premises for various social needs, and private houses. Practical utility. The prospects of building with precast and cast-in-place structures for restoration of facilities in Ukraine, which should be carried out according to versatile adaptive designs, has been proven. For the implementation of the technology of building with precast and cast-in-place structures, there is a need for further research on organizational and technological reliability, increase in manufacturability, economic efficiency, flexibility of solutions for various facilities and construction conditions

Precast structures for multi-storey buildings can be designed with economy, safety and high performance. However, depending on the height of the building and the intensity of the lateral loads, the lateral stability system must be carefully chosen in order to maximize the global structural performance. In Brazil, the most common method for lateral stability is achieved by moment resisting precast-frames, wherein the moment-rotation response of the beam-column connections are responsible to provide the frame action, which will govern the distribution of internal forces and the sway distribution along the building height. On the other hand, in Europe, bracing systems comprised by shear walls or infill walls are mostly used, wherein beam-column connections are designed as hinged. The aim of this paper is to present a comparison between these methods for lateral stability, applying nine structural simulations with moment resisting precast-frames, shear walls and infill walls solutions, divided in three groups - 3 building with 5 storeys (21 meters high), 3 buildings with 10 storeys (41 meters high) and 3 building with 20 storeys (81 meters high). All first storeys are 5 meters high, while all the others are 4 meters high. The results from all structural analyses are compared. As conclusion, while moment-resisting beam-column connections are more feasible for applying in low-rise precast buildings, the use of shear walls and infill walls are more efficient for tall buildings due to decrease of lateral displacements, having a reduction of second order effects but also increasing the reactions at the foundations of bracing elements.

The structural stability, constructability, economic feasibility, environmental-friendliness, and energy efficiency of hybrid composite frame systems have been demonstrated by practical application and research. A hybrid composite frame system combines the economy of precast concrete structures with the constructability of steel frame structures, including erection speed. Novel composite frames will ultimately maximize the efficiency of structural design and facilitate construction. This paper presents hybrid precast frames, which are precast composite frames based on a simple connection between precast concrete columns and beams. The hybrid precast frames designed to resist gravity loading consist of PC columns, PC beams, and steel inserted in the precast members. Steel sections located between the precast columns were simply connected to steel inserted at each end of the precast beams. Dynamic analysis of a 15-story building designed with the proposed composite frame was performed to determine the dynamic characteristics of a building constructed of hybrid frames, including frequencies and mode shapes.

 Construction processes, particularly floor slab systems, can be executed using precast/precast methods as technology advances. Compared to traditional methods, which need more time and production expenses, precast/precast methods are more cost-effective for floor slab formwork, neater, and have a more consistent finish. This study is based on an eight-floor building project with 92 residential units on a 3,500 m2 plot of land and a 1,700 m2 building size. This investigation used two technologies: conventional precast slab and full slab precast. The purpose of this research is to compare the most cost-effective strategy for reducing production costs on floor slab work for the construction of the case study. Based on the calculation results, the full slab precast method is 14.31% or around Rp. 980,508,000 is more economical than the conventional method. For the conventional method, the total cost is Rp. 3,914,657,000 while for the precast method, the result is Rp. 2,934,149,000.

Around New Zealand there has been an increasing trend of ‘hybrid’ multi-storey buildings that combine reinforced concrete walls with structural steel framing systems. This study aims to characterise and understand this type of building, focusing on buildings constructed in Auckland and Christchurch from 2014 onwards. Drawings from a total of 50 buildings were reviewed, and their structural features were documented, including building use, building height, lateral load resisting system, ductility, wall configuration, wall construction method, steel framing system and suspended floor system. Meetings with structural engineers were conducted to validate the review findings and to further understand design principles and decisions that lead to these outcomes. A typology comprising five building types with distinct lateral load-resisting systems was proposed based on the building review. Results showed regional differences between Auckland and Christchurch, owing to building use and seismic hazard in the respective cities. Auckland buildings surveyed tended to be residential buildings five storeys or higher made of precast walls connected with steel beams. Christchurch buildings, on the other hand, were primarily commercial buildings three to seven storeys high with dual frame-wall systems. Structural connections between steel frames and concrete walls were also documented, showing that bolted connections with headed stud embedment were most common. The results can be used to identify critical aspects of these mixed structural systems for further investigation and to develop archetype building designs that can be used for modelling and testing.

Purpose The purpose of this paper is to discuss the principles for managing precast concrete (PC) building in the context of Malaysian maintenance practice. A large number of clients/contractors in a PC building maintenance project faced many issues due to poor service delivery, less-competent contractor and defect repetition. Meanwhile, conventional method practices tend to be ineffective in Malaysian PC building. Design/methodology/approach Case studies were used to investigate the practice of maintenance management with eight professional engineers working in the Malaysian PC building maintenance departments. Findings Interviews were held with these departments and content analysis was used to identify themes that demonstrate effective PC building maintenance management practice. The frontline approaches (new system development with the integration of BIM) and underlying approach such as decision making in defect diagnosis are presented to address the maintenance management problems on PC building such as defect repetition and less-competent contractor. Originality/value The underlying approaches include sustaining existing maintenance quality and providing decision making in diagnosis support while the frontline approaches include the use of emerging technologies, efficient control of building performance-based design and monitor the defect component operation in maintenance.

Full textAbstract:
Architectural precast concrete cladding systems are considered non-load bearing wall systems and are designed primarily to transfer their self-weight and out-of-plane lateral loads to the supporting building structure. They are typically not designed for significant structural in-plane forces resulting from cladding-structure interaction. In fact, modern earthquake-resistant design requires that these cladding panels be isolated from the lateral force-resisting system. Finite element technique was employed to study precast concrete panels and special modeling strategies were developed for panel connections to the structural frame. The precast concrete panel was designed to participate in the building lateral force-resisting. Finite element modeling techniques were adopted to better understand the strength and stiffness characteristics of these concrete cladding panels subjected to significant in-plane loading. Good correlation was obtained between finite element modeling results and existing experimental results. The analytical results were used to develop a simplified mathematical model that can be incorporated into suitable building models to evaluate its performance as a lateral force-resisting system to withstand earthquake-induced lateral loads.

Studying the structural behaviour of adobe systems in Colombia became extremely relevant after the 1999 earthquake in Armenia due to these systems' good performance during seismic events. These studies were aimed at modernising adobe house construction (by increased use of technology) and providing minimum requirements for them having a suitable degree of seismic resistance, thereby avoiding their collapse. Besides, if it is taken into account that guadua (the main material used in these systems) represents a cheap and profitable material which is socially and culturally-accepted in most of the country, then one has an alternative, unconventional material available which may be suitably used in constructing cheap, functional and safe housing (its limitations and best use having been identified). The foregoing gave rise to the present investigation in which an experimental evaluation was made of a guadua frame system using two types of prefabricated panels in adobe, under horizontal load. Two fullscale frames were built with guadua at the Universidad Nacional de Colombia's School of Engineering in Bogota; the frames' ability to dissipate energy and support inbuilt rigidity (by stiffening them with precast adobe) was tested and strength-deformation curves were experimentally found. Extremely encouraging results were obtained as drift was reduced by roughly 50% and the system's resistance was increased by more than 40%. Mathematical models were also constructed for comparing experimental results with analytical ones.

The subject of the study is building systems and building construction technologies, which are considered in order to study the development of industrial construction methods in St. Petersburg and predict trends in technical progress in the field of industrial construction methods. The prerequisites for technological progress in the construction complex of St. Petersburg is the development of the industry of material and technical resources of construction, namely the production of new building materials, structures, construction equipment, fixtures and construction machines, as well as small-scale mechanization and tools. This inevitably becomes the reason for the appearance in construction of more advanced building systems erected by industrial methods. In the course of the study, building systems were evaluated by the methods of an expert survey of specialists according to a previously developed questionnaire, in which there were mutually incomparable criteria reflecting the architectural, strength and economic characteristics of building systems of industrial production. The results of an expert assessment of building systems became the basis for determining the rational scope of prefabricated and precast-monolithic construction and identifying trends and promising directions for the development of industrial construction methods and scientific research in this area.

The aim of this research is to investigate the sustainability of design for deconstruction on saving: natural raw materials, embodied energy and carbon emission of steel buildings. A methodology is devised to account for designed for upcoming reclaim at the early planning phase. The procedure is relied on PAS2050 method. A steel structure building of two bays of size (6m x 8m) and of 4m height is devoted as a case study to assess the methodology. In this case study, three different floor systems are suggested: composite steel deck, hollow core precast concrete planks, and demountable precast composite floor system. The reduced quantity of embodied carbon energy is estimated through considering the steel building. The calculation of embodied carbon of the three models is relied on records of the Inventory of Carbon and Energy (ICE). The results show that CO2 emissions from the building can be dropped around 50%, when design for deconstruction strategy is considered. Design standards and codes lack a little procedure to follow. Therefore, this study also outlines some helpful specifications, guidelines, and detailing of design for deconstruction of steel buildings.

The paper deals with a system of precast floor plates from lightweight concrete intended mainly for building of family houses and residential construction. The developed system has two types of precast floor plates made from lightweight concrete: floor plates for floor systems and solid section floor plates. This paper describes solid section floor plates. The unambiguous advantage of lightweight concrete floor construction is weight lower by as much as 37% compared to floor structure made from common concrete, while bearing strength remains unchanged as well as high fire resistance. This type of floor slabs has also been successful in the system of assembled prefabricated houses thanks to its lower weight and elimination of the wet construction process.

Robustness of reinforced concrete (RC) structures is an ongoing challenging research topic in the engineering community. During an extreme event, the loss of vertical load-bearing elements can activate large-deformation resisting mechanisms such as membrane and catenary actions in beams and floor slabs of cast-in-situ RC buildings to resist gravity loads. However, few studies have been conducted for precast concrete (PC) buildings, especially focused on the capacity of such structures to withstand column loss scenarios, which mainly relies on connection strength. Additional resistance resource and alternate load paths could be reached via tying systems. In this paper, the progressive collapse resistance of a PC frame building is analyzed by means of nonlinear dynamic finite element analyses focusing on the fundamental roles played by beam-to-column connection strength and tying reinforcement. A simplified modelling approach is illustrated in order to investigate the response of such a structural typology to a number of sudden column-removal scenarios. The relative simplicity of the modelling technique is considered useful for engineering practice, providing new input for further research in this field.

Full textAbstract:
The 2010–2011 Canterbury earthquake sequence provides a rare opportunity to study the performance of modern structures designed under well-enforced, evolving seismic code provisions and subjected to severe ground shaking. In particular, New Zealand makes widespread use of precast concrete seismic systems, including those that are designed to respond identically to cast-in-place concrete structures (emulative systems) and, in more recent years, those that take advantage of the unique jointed properties of precast construction. New Zealand building construction also makes extensive use of precast elements for gravity systems, floor systems, stairs, and cladding. Although not always classified as part of the primary seismic force-resisting system, these “secondary” elements must undergo the compatible displacements imposed in the earthquake. Damage evaluations for several of these structures subjected to strong shaking provide the ability to examine the differences in seismic performance for systems of distinct design intent and standards, including the performance of secondary elements.

Precast concrete buildings in Industrialised Building Systems (IBS) are constructed of multiple pieces of structural members joined together using a variety of methods. The use of precast concrete wall panels has become increasingly popular in modern construction practices. One critical aspect of precast concrete wall panels is their connection to the adjacent walls. Various of wall-to-wall connections have been used in the IBS based construction. However, for non-load bearing application, the use of dapped connections for precast wall made with recycled concrete aggregate (RCA) is still limited and unexplored. This study aims to evaluate the structural performance of horizontally light reinforced dapped (HLRD) connections for precast wall panels made with RCA. The investigation includes experimental testing that includes three pair of specimens subjected to uniformly distributed monotonic loading to evaluate their strength capacity, strain, and deflection behaviour as well as the resulting crack propagation throughout the test. The connection displays brittle behaviour by developing a few line cracks and having a significant deflection before failure. The findings of this study will contribute to a better understanding of the behavior of HLRD connections and provide preliminary guidance for their design in precast concrete wall panels.

Full textAbstract:
This research aims to present a new generation of seismic-resisting systems designed for precast reinforced concrete (RC) bridge piers in modern sustainable cities to withstand moderate to high seismic activity. The proposed system consists of two self-centering (SC) systems operating in parallel to bring together all features of the required resiliency during a seismic action. The first/main system is a hollow core precast segmental bridge column, and the second is composed of an SC precast unit and energy dissipation (ED) steel reinforcements positioned in the main pier segment’s hollow core. To study the performance of the proposed system, a finite element model was first developed to capture the behavior of experimentally tested precast bridge columns. After validation, the created model was systematically studied to investigate the performance of the entire proposed system under cyclic loading. The effects of three parameters related to the ED system were investigated, including the reinforcement ratio, the unbonded length of ED bars, and the SC post-tensioned force ratio. Furthermore, the impact of FRP wrapping on the lower part of the core column of the ED system was also investigated. An analytical model predicting the characteristic points of the lateral response of the proposed system based on the superposition concept is also proposed. The FE results showed that the entire proposed system is a new design-based resilient system with the ability to dissipate energy without compromising the SC capacity of the main resisting system. Compared to the typical precast hollow core segmental column, a 6% reinforcement ratio of the ED unit can cause a 60% increase in lateral resistance and a 220% increase in the ED capacity. The analytical model can successfully be applied in the design of the proposed system to provide customized ED capabilities and controlled lateral resistance.

Innovative construction practices drive progress in the development of sustainable, efficient, and high-quality residential buildings. Yet, this practice in residential buildings remains limited. This study investigates the innovative construction practices applied in the development of Harmoni Elmina 1, with a focus on the integration of Industrialised Building Systems (IBS) and Building Information Modelling (BIM). Through a case study approach, key innovations were explored through interviews and project documentation analysis. BIM played a crucial role in the planning, design, and construction stages, reducing error, waste, and risk while enhancing cost efficiency and project progress. Moreover, 10 IBS components, including precast concrete, bubble deck systems, precast reinforced concrete, and prefabricated components, were utilized, further enhancing construction efficiency and quality. The findings demonstrate that integrating BIM and IBS significantly improved project performance, conserve project duration by 28-33%, preliminary cost by 30%, and achieving near zero construction waste. Inclusively, this case study offers valuable insights for industry professionals by showcasing best practices in BIM and IBS integration, providing a model for improving project outcomes, resource efficiency, and sustainability in the built environment. Projects like Harmoni Elmina 1 highlight the transformative potential of innovation in improving living standards, and promoting more sustainable built construction industry.

The design and employment of envelope components showing high thermal performances for new buildings and deep renovations must take into account the overall impact of the production process in terms of environmental sustainability. To this end, precast construction solutions and secondary raw materials provide added value to the energy quality of building products. With regard to the abovementioned issues, the paper is focused on the performance optimization of expanded polystyrene-reinforced concrete (EPS-RC) precast bearing walls, already developed and patented within a previous research project entitled “HPWalls. High Performance Wall Systems”, and herein improved according to two complementary requirements: on the one hand, the addition of recycled EPS particles to the concrete mixtures and, thus, the assessment by lab tests of the correlation between the thermal and mechanical properties for several mix-design specimens; on the other hand, a study using analytical simulations of the most suitable joint solutions among modular panels in order to prevent thermal bridges. The achieved results validate the proposed optimization strategies and provide reliable data for market applications in the building sector.

Usage of the floor-lifting method for buildings erection with precast-monolithic reinforced concrete frames of «KUB» or similar frame system was reviewed in the article. Analysis of technological features of proposed method was done. Advantages and disadvantages of proposed method usage were listed. Opportunity of floor-lifting method of reinforced concrete frames buildings erection in dense areas usage was justified. Usage of the floor-lifting method for erection of buildings with precast-monolithic reinforced concrete frames of «KUB» or similar frame system allows to reduce the works complexity due to the complete refusal to use the equipment for the verification and temporary fixing of slabs individual elements and the operations exclusion associated with the retrieval and temporary fixing floor slabs elements. Proposed method usage allows to move majority of assembly operations to the ground floor level, which can significantly increase the industrial safety level, improve the work and control quality. Reducing the installation parameters values, allows to use less powerful self-propelled cranes for building frame elements installation, in some cases, completely refuse to use the tower cranes. It makes sense to use this building frameworks erection method in dense urban areas. The main disadvantage of this method is the high demanding quality of the slabs elements production. Because the surface of the slab is the basis for the next floor slab, inaccurate factory production will not allow the exact slabs elements installation in the required position. Â

Abstract In the construction of vertical buildings, the implementation method used affects the productivity of construction. The development of construction system innovation in Indonesia which continues to grow has led to a new system, one of which is the precast system. Precast systems have been proven to be able to increase productivity in terms of construction time and costs, as well as the value of waste costs, which results in little from conventional methods. The main objective of this study was to compare the efficiency of the method of implementing floor slabs in the field by comparing the variables of field implementation, costs, time, quality control, and material waste costs of the conventional and precast half - slab methods. The analysis was carried out using the unit price is based on the Jakarta Worker’s Wage Unit Price 40 year XXVII - 2021 edition. The index coefficient (conventional) refers to the Minister for Public Works and Human Settlements Regulation No. 1 of 2022, and the index coefficient (precast half slab) refers to SNI 7832:2012. Scheduling was performed using Microsoft Projects. The results show that the precast half - slab method is more efficient than the conventional method.

Full textAbstract:
To improve the post-earthquake resilience evaluation of concrete buildings with various construction types, this study presents a generalized recovery-based framework that ext-ends the FEMA P-58 methodology. The proposed method introduces a dynamic repair scheduling approach that incorporates two key construction-related parameters: the prefabrication ratio and the types of prefabricated components. These inputs govern the allocation of parallel or sequential repairs, enabling a more accurate estimation of recovery trajectories and downtime. Functional loss over time is modeled through component-level repair sequencing combined with mobilization delays. A case study involving three four-story prestressed concrete frame buildings (cast-in situ, partially prefabricated, and fully precast prestressed concrete (PCaPC) with mortise–tenon (MT) connections) demonstrated the framework’s applicability. The results show that higher prefabrication levels lead to significantly shorter median repair times, with up to a 97-day reduction observed for the fully prefabricated frame. Additionally, recovery differences emerge even between buildings with the same prefabrication ratio but different component configurations. Compared to conventional assessment methods, the proposed framework avoids the overestimation of mobilization and repair duration, offering a practical tool for the design and performance assessment of resilient precast and hybrid concrete building systems.

Difference between conventional and precast systems required design adjustments. Adjustments began with preliminary design of structural and application of one-way floor slabs (HCS). From structural analysis result, stability of the structure calculate along corbel connection design. From redesign results found difference amount of tensile reinforcement in the beam ranges from 2 to 4 due one-way slab load distribution. Differences in the arrangement of main reinforcement column due differences of width-height column to strengthen weak axis column. HCS slab with thickness of 20 cm to lighten the weight of structural elements. Corbel as connectors resist shear at joint as the redesign results meet the structural stability requirements and the requirements of public buildings. Keywords: Precast Concrete, HCS, Corbel
