Staged‐construction analysis of high‐rise buildings: A literature review and future perspectives

Abstract

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.
