Review of structural systems for tall buildings - Vol.96(11), Nov - Mumbai ACC LTD 2022 - 7-17p.
The effects of lateral loads on tall buildings are pretty significant. Therefore the influence of these actions must be considered from the very beginning of the design. In high-rise building, the structure’s construction is greatly influenced by the type of lateral system provided. The selection of an appropriate lateral structural system plays an essential role in the structure’s response. The taller and slenderer a building, the more critical the structural factors become, and the more necessary it is to choose an appropriate structural form. This article reviews the rigid-frame structural system, braced-frame structural system, and wall-frame structural system. Various models of a RCC tall building are made, and the results of each model are observed for considered structural form. The aim is to find the suitability of the structural system with an increase in height, parametric investigation of the wall-frame, and the braced frame structural system. The structural models are analyzed in ETABS software to study the effect of the height of buildings on the performance of these buildings under lateral loads (seismic forces and wind loads). The linear dynamic response spectrum method is used for the analysis of the structure.
