Abstract
Staged‐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.
期刊介绍：
The Structural Design of Tall and Special Buildings provides structural engineers and contractors with a detailed written presentation of innovative structural engineering and construction practices for tall and special buildings. It also presents applied research on new materials or analysis methods that can directly benefit structural engineers involved in the design of tall and special buildings. The editor''s policy is to maintain a reasonable balance between papers from design engineers and from research workers so that the Journal will be useful to both groups. The problems in this field and their solutions are international in character and require a knowledge of several traditional disciplines and the Journal will reflect this.
The main subject of the Journal is the structural design and construction of tall and special buildings. The basic definition of a tall building, in the context of the Journal audience, is a structure that is equal to or greater than 50 meters (165 feet) in height, or 14 stories or greater. A special building is one with unique architectural or structural characteristics.
However, manuscripts dealing with chimneys, water towers, silos, cooling towers, and pools will generally not be considered for review. The journal will present papers on new innovative structural systems, materials and methods of analysis.
