Abstract

Lateral loads such as earthquake and wind loads play a governing role in the design of high-rise buildings. Consequently, providing adequate lateral rigidity against such loads in high-rise buildings is a major concern for structural engineers. A shear wall is one of the vertical elements which are used in buildings to fulfil lateral rigidity requirements. But its location and arrangement should be proper to effectively resist lateral loads, The main objective of this research is to identify buildings with and without shear walls that adequately resist lateral load by utilizing finite element-based ETABS software that can minimize the displacement and drift of buildings induced by the earthquake and wind load. The equivalent static approach based on the IS Code was used to compute seismic loads. The story displacements and drifts results were obtained using four load combinations from the IS Code. It has been observed that shear walls located in the center, in the shape of a core, perform well against lateral loads. The displacement at the top of such a building is around 2.5 times less than the displacement at the top of a building without a shear wall. Shear walls near corners have the lowest effectiveness.
