Comparative Analysis Of The Structural Response of A G+8 Storied Building With Varying Shear Wall Placements Using ETABS.

Abstract

This study presents a comparative analysis of three structural building models subjected to seismic and wind load conditions. The objective is to evaluate their performance with respect to interstorey drift limits, total sway limitations, and overall structural efficiency in accordance with applicable code requirements. Each model was analyzed using ETABS to obtain lateral displacement and drift responses under EQx, EQy, Wx, and Wy load cases. The results show that Option -2 provides superior performance, satisfying both drift and sway criteria for all load combinations. In contrast, Option -1 fails to meet the drift and sway requirements in the EQx direction, indicating comparatively low lateral stiffness. Option -3 performs better than Option -1 but fails the sway limit in the EQx case, demonstrating the need for additional stiffness enhancement. Among the three, Option -2 not only ensures structural safety and full code compliance but also proves to be the most economical solution, offering optimized material usage while maintaining adequate lateral resistance. This study concludes that Option -2 represents the most effective and efficient structural configuration for the building under the evaluated loading conditions.
