THE SUITABLE LOCATION FOR SHEARING WALLS ON SOFT STOREY IN HIGH RISE BUILDINGS TO INCREASE IT’S STIFFNES

In present era demand for land is high for residential, commercial and industrial growth of any country and also we need to preserve land for agriculture. Due to this there is increase demand for high rise structures. These tall buildings are subjected to lateral forces due to wind and earthquake. Social and functional needs like vehicle parking, shops, reception etc. are compelling to provide soft storey in high rise building. Soft storey can form at any level of a high rise building to fulfil required functional necessity and serve various purposes. Soft-story formation due to sudden change in the vertical stiffness between following stories. To improve the dynamic response of these slender tall buildings different forms of structural system need to be adopted. One of the structural forms for RC buildings is by using shear walls. Lateral forces due to wind or earthquake are usually resisted by shear walls which are provided parallel to the direction of lateral load. These shear walls, by their shearing resistance and resistance to overturning, transfer the lateral loads to the foundation. In this study different location of shear wall is studied. Dynamic Analysis is carried out using response spectrum method.
