Abstract

Abstract: Multi-storeyed buildings are tall structures with multiple floors designed for diverse purposes. Base shear represents the total lateral force a building's foundation must withstand during seismic events. Reducing base shear enhances structural safety, design efficiency, and overall building performance. It enables cost-effective designs and fosters sustainability in multistoreyed constructions. Effective management of base shear is pivotal for ensuring safety and optimizing the structural integrity of high-rise buildings. This research paper aims to reduce the base shear in multi-storeyed buildings. To achieve this objective, a comprehensive analysis was conducted on a G+15 storey building with series of seven model cases abbreviated form BSR Case 1 to BSR Case 7. The comparative analysis revealed that when sizes of the column at a particular level decreases, the base shear decreases that enhances the structural parameters and hence BSR Case 7 observed as optimum case that reduces the base shear and performance of multi-storeyed building.
