This document analyzes the effectiveness of different structural configurations for resisting lateral loads in a 10-story building subject to seismic activity. Two structural models are considered: a normal building frame and a dual system with shear walls and bracings placed at the building corners. Both models are analyzed using time history analysis in STAAD-Pro. Results show that the dual system experiences significantly less lateral deflection, with displacements reduced by 86-89% compared to the normal frame building. Additionally, the dual system sees only minor reductions in maximum shear force and bending moment compared to the normal frame building. Therefore, the dual system with corner shear walls and bracings provides greatly enhanced seismic performance over a normal framed building.
