REVIEW OF STRUCTURAL SYSTEMS FOR TALL BUILDINGS

Abstract

The effects of lateral loads on tall buildings are pretty significant. The influence of these actions must therefore be considered from the very beginning of the design. In high-rise structures, 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. Based on the different structural systems, some of the structures are rigidframe structures, braced-frame structures, shear wall structures, wall-frame structures, framedtube structures, outrigger-braced structures, suspended structures, spaced structures. The taller and more slender a building, the more critical the structural factors become, and the more necessary it is to choose an appropriate structural form. This project reviews the following structural form: Rigid-frame structural system, Braced-frame structural system, Shear wall structural system, and Wall-frame structural system. Various models of a tall building are made, and the results of each model are observed for considered structural form. This project aims to find the suitability of the structural system with an increase in height, parametric analysis of shear wall with frame and braced frame structural system, parametric study of shear wall with frame includes the variation in positions of the shear wall and height of the shear wall. And parametric analysis of braced frame structural system involves suitability of different configurations of the bracing and best location of bracing. The structural models are analysed in ETABS 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.
