Many connection systems are available that can transfer tension and shear loads from a precast concrete wall panel to a floor slab. However, due to the insufficient anchor depth in relatively thin precast concrete panels, it is difficult to attain adequate ductility and stiffness to ensure structural integrity. Based on the authors’ previous research results, the supplementary reinforcement of embedded steel plates in precast concrete wall panels can enhance stiffness while maintaining allowable displacement and ductility. In this study, three full-size tilt-up precast concrete panels with embedded steel plates were fabricated. Lateral cyclic loads were applied to full support structures consisting of a precast concrete wall panel and a foundation. The test results were compared with the results predicted using existing code equations found in the American Concrete Institute 318-14 and the Prestressed Concrete Institute Handbooks. The test results confirm that the supplementary reinforcement of thin precast concrete wall panels can provide (i) the required strength based on current code equations, (ii) sufficient ductility, and (iii) the energy dissipation capacity to resist cyclic loading.

The aim of the paper is to demonstrate the widely presented benefits of modular construction as compared with traditional construction method. A case study of family house construction by modular building method and traditional method is used to examine the structural, economic and time indicators of individual construction methods. The results are presented in tabular and graphical outputs and are compared each other in regard to different technological parts of the building. The paper provides the comparison of economic and time indicators resulting from budgets and time schedules of construction that are executed for different variants. Such comparison demonstrates exactly the benefits of modular construction. The building based on building modules consisted of steel bearing structure and enveloped by sandwich panels is adopted as the selected modular construction technology. The different variant, applied for comparison of modular and traditional construction, is represented by the building with comparable thermo-technical characteristics, constructed by traditional masonry method.

Flexible Connections

To explore the performance of the flexible nodes between the precast concrete wall panel and the frame structure, a steel truss is used as an analogue of the frame structure to develop a test. In the test, one precast concrete wall panel was installed on the steel truss, and the connection nodes are designed to be able to slip vertically. Different horizontal forces were exerted on the steel truss to form certain drifts, and the deformation of panel and the slipping performance of the connection nodes were explored. It is found that precast concrete wall panel wont deform under the influence of the drifts, while the connection nodes between the frame structure and the panel were found to slip. The results show that the design of slipping connection node has enough reliability.

The development of prestressed concrete is growing rapidly as the widespread construction technology. The use of prestressed concrete supports infrastructure development in Indonesia , especially Kualanamu Railway overpass in the city of Medan that use Box Girder with sectional height 2400 mm as a structural component . The case study of prestressed concrete box girder Railway flyover with spans of 40 meters Kualanamu explain sectional effectiveness girders whereare internaltendons filled in strand steel cables. 12.7 mm totaling 60 pieces. Further analyzing the percentage loss of prestressing force that occurs in the tendon due to the shortening of the elastic, friction on the tendon , creep , shrinkage of the concrete and so on. Additionally introduced step by step production process prestressed concrete box girder ranging from reinforcement to casting in the precast concrete plant.Keywords: Prestressed concrete , box girder, loss of prestressed
