Shear wall is a structural member used to resist lateral forces parallel to the plane of the wall. Shear wall resists
the loads due to cantilever action. In other words, Shear walls are vertical elements of the lateral force resisting system
(wind and seismic forces). This study aims to compare the seismic performance of two model of G+6 story real life
reinforced concrete building located in Zone 3. Model 1 is generated with special moment resisting frame (SMRF) as the
lateral load resisting system whereas same building is converted into model 2 which consists of number of shear walls
replacing the columns (SW). The objective of the present study is to compare the seismic performance of the two models. The
designs of the buildings were carried out by response spectrum analysis. Nonlinear dynamic responses of these buildings
were analyzed using Etabs. The base shear, storey drifts, storey displacement and storey stiffness from the analysis were used
for the evaluation of the responses of the building. The quantities of steel and concrete consumed are calculated and
compared. It has been found that the building with R.C. shear wall is economical and shows better response then the same
building with special moment resisting frames.
