The trend towards progressively taller structures has demanded a shift from the traditional strength based design approach of buildings, to a focus on constraining the overall motion of the structure. Now a day’s reinforced concrete (RC) wall-frame buildings are widely recommended for urban construction in areas which are prone to earthquake. Construction of shear walls imparts a large stiffness to the lateral force resisting system of the RC building. Proper detailing of shear walls can also lead to ductile behavior of such structures during strong earthquake shaking. One of the main parameters influencing the seismic behavior of shear wall frame buildings is the shear wall area ratio and shear wall area ratio need to be studied. Thus an analytical study is performed to evaluate the effect of Shear Wall Area to floor area ratio (SWA/FA ) on the seismic behavior of multistoried RC structures with soft storey at ground floor. For this purpose, 9 building models that have Five, Nine and Twelve stories with various SWA/FA in both directions are generated. Then, the behavior of these building models under earthquake loading is examined by carrying out Response Spectrum Analysis and Linear Static Analysis using structural analysis software Etabs. Response Spectrum Analysis and Linear Static both are carried out according to seismic code IS 1893:2002
