Abstract:
Soft-story buildings are structurally vulnerable due to discontinuities in their stiffness and strength, especially when subjected to lateral loads during seismic events. This study investigates the seismic retrofitting of soft-story high-rise buildings using shear wall stiffeners. A G+30 storied building is modelled using ETABS 21 software, analysing the structural response of retrofitted and non-retrofitted conditions across varying soil types. Key parameters studied include lateral displacement, storey drift, base shear, and column forces at the bottom, middle, and top soft stories. Results indicate significant improvements in structural performance upon retrofitting, particularly with shear wall placement in X and L configurations.
