Effectiveness of Shear Wall in High-Rise Residential Buildings under Seismic Loading As Per BNBC 2020 Regulations

Abstract

In RC building, shear walls are commonly used to counteract lateral loads. Recent advances in structural engineering have been made with the intention of mitigating the effects of earthquakes and high winds. The population crisis can only be resolved by vertical growth rather than horizontal expansion. Reinforced concrete structural walls, also known as shear walls, are crucial in earthquake-resistant building design. The walls effectively brace and resist lateral loads. To resist lateral forces, many tall structures employ shear wall systems. Because of their high in-plane stiffness and strength, shear walls are widely used in structural engineering. Consequently, studying how buildings react during earthquakes is crucial, and seismic shear walls play a crucial role in this. Both shear walls and frame constructions are analyzed in this study. Two models are produced when a shear wall is absent. Generating G+10 RC frame models with height-dependent member dimensions allows for the inclusion or exclusion of shear walls. The models for seismic zone II are analyzed by ETABS 2016 utilizing the Static Method and the Response Spectrum Method. All models are compared with respect to a number of criteria, such as their lateral displacement, story drift, base shear, and mode shapes (with and without shear walls). There is a detailed explanation of shear walls. The seismic response of the building is mostly determined by the characteristics of the seismic shear walls.
