To Study the Distribution of Seismic Load in Shear Wall Frame Dual System Using SAP2000

Abstract

Shear wall is one of the most important structural member used to resist the lateral load in high rise building. Shear wall has high in plane stiffness and strength which resist both lateral loads and the gravity loads. Shear wall with frame is known as dual structural system or wallframe structure which is most effective and adequate in resisting of lateral load like earthquake load. The scope of present work is to study the distribution of seismic forces between the shear wall and moment resisting frame. The residential G+14 building is analyzed for earthquake load by considering two type of structural system. i.e. Frame system and shear wall frame dual system. Analysis is carried out by using SAP2000 in which dynamic analysis has been done using non-linear dynamic (Time History Method) and modal analysis. By using Non Linear analysis, stiffness coefficient ratios have been found for shear wall and moment resisting frame which determines the distribution of earthquake load on the building.
