A large proportion of world’s population lives under higher seismic risk region so there is a need of construction technologies which resist higher seismic forces and Shear wall is such type of technology. Shear wall are used as an efficient way to resist lateral load in RC building. Shear wall stabilize the whole structure against the effect of strong horizontal seismic loading and impart stiffness to the building. The main goal of this research is to find out of Displacement of the building. The present study is an attempt to understand the effectiveness of story displacement on different storey height of building. Four different height of building G+5 to G+20 every five incremental story has been taken. The response spectrum analysis of building of portal bracing in place of shear wall was carried out using STAAD PRO software. At the end, building response parameter Story Displacement was compared.
