COMPARATIVEANALYSISOFSHEARWALL CONFIGURATIONS AT SOFT STORY AND FULL BUILDING HEIGHT ON THE SEISMIC PERFORMANCE OF MULTI-STORY STRUCTURES

Abstract

When compared to constructions without shear walls, shear walls greatly increase story 
shear, base shear, and stiffness. The seismic performance of seven models with T, C, and H
shaped shear walls at soft story and full height was compared using IS 456:2000's zone 
factor (Z = 0.16). Compared to soft-story shear walls and no-shear-wall models, full-height 
shear walls (T, C, and H) greatly increase story shear. Similar shear is produced by soft
story T, C, and H shear walls—slightly better than none. In shear at both levels, Model 5 (C
section, full-height) performs better than T and H. For every model, base shear stays the 
same. In every situation, C-section shear walls work well. While Model 5 leads in Y
direction stiffness (Ky), Model 4 (C-shaped, soft-story) improves X-direction stiffness (Kx, 
kN/m). Compared to full-height walls, soft-story shear walls display lower Ky
