“…Some researches focused on the deflection of PT slabs as Nawy and Chakrabarti. 90 Collins and Mitchell 87 and Naaman 91 presented equations for predicting PT slab camber depending on tendon profile and concrete modulus of elasticity at the time of stress transfer. The methods reported by the aforementioned authors were commonly utilized to measure the serviceability of traditional structures, not considering the additional deformations developed by SCA.…”

SummaryStaged‐construction analysis (SCA) has recently become a noticeable trend for estimating the design forces and deformations for high‐rise buildings (HRBs). SCA is a nonlinear step‐by‐step analysis that simulates the construction activities and conditions. It is a numerical simulation that considers loading history during construction, time‐dependent material behavior, environmental conditions, and any special measures taken by contractors to limit differential axial shortening during the construction process. However, building codes and guidelines do not provide adequate provisions that clearly identify how to approach this type of analysis. This paper presents a comprehensive state‐of‐the‐art review on how SCA was previously adopted in theoretical research and how it was applied in real buildings. It begins by critically reviewing different research work on SCA. Afterward, the paper puts forward the recent fundamentals of conducting SCA. Then, a series of studies about verifying SCA as practical analysis procedure using field measurements are then presented. In addition, the current paper reviews how SCA can specifically affect post‐tension slabs. Based on this review, several recommendations are provided to help in shaping the future code provisions, add to the development of recent practices, and inspire future research. The conducted review concludes that more investigations should be performed to better understand the effect of considering SCA on the deformations and design forces during HRB analysis.

Background: Slab weight can be reduced by replacing the amount of concrete in the tensile area with the utilization of modification polyvinyl chloride pipe as cavity without reducing the flexural strength because the nature of concrete is weak against tensile strength. Methods: This research with the experimental method using static load. The setting of tools refers to the American Society for Testing and Material E 2322, bending analysis is used moment coefficient method, deflection by applying Ugural and Navier method, and shear analysis using Indonesia National Standard 03-2847-2019. Results: The specimens consist of solid plates with a thickness of 140 mm and hollow plates with a thickness of 140 mm and 159 mm. The maximum load capacity solid plate is 410.642 kN, while the hollow plates (140 mm) is 335.18 kN, and for the hollow plates 159 mm is 396.257 kN. The solid plate’s stiffness is 16.321, the hollow plates 140 mm is 14.787 and the hollow plate 159 mm is 24.194, while the ductility is 1.993 on solid plate, the hollow plate 140 mm is 2.014, and the hollow plate 159 mm is 1.862. The solid plate’s damage is flexural, while the two hollow plates are a combination of bending and shear damage. The crack pattern on the solid plates is flexible, while the crack pattern on both hollow plates is a combination of flexural cracks and shear cracks. Conclusion: The use of modified polyvinyl chloride pipes can be recommended in the structure of the plate. There is a small, insignificant difference in the flexural behaviour between the solid plate and hollow concrete reinforced slab with the utilization of Polyvinyl Chloride.
