Abstract

AbstractThe high-rise buildings, especially having asymmetric plan, are highly susceptible to seismic force and high wind pressure. Using shear wall and bracings, it may be possible to arrest the deformation of a structure due to high seismic force and wind load. The present paper is an attempt to perform a comparative study between the effectiveness of a shear wall and bracing system of high-rise structure having an asymmetric plan. For understanding the effect of the shear wall and bracing system in the buildings having asymmetric plan in a better manner, a building having symmetric plan of the same height has also been incorporated in this study. Shear wall and RCC bracings have been provided at different locations on the boundary of two different G+25 buildings having asymmetric plan as well as the building with symmetric plan. The study has been performed using the finite element software STAAD.Pro. The maximum base shear, storey drift at each floor level, and maximum base moment under seismic and wind forces are calculated for the buildings with shear wall and bracing systems.KeywordsHigh-rise structureAsymmetric planShear wallBracingsBase shearStorey driftBase moment
