Abstract

Though the infill wall and the shear wall had been generally considered as a non-structural element in analysis and design as a common practice but, now it is a well-known fact they have their own strength and stiffness. Therefore along with the study of the importance of infill walls and shear walls, their combined effect due to different arrangements and locations is a matter of study. The present study focuses on analyzing the seismic behaviour of a building structure to identify the basic effect of elements like in filled and shear walls by appropriately selecting and providing their respective material and geometrical properties. The purpose of an investigation is to study the response parameter such as base shear, lateral displacement, moments and column shear of a G+5 storied building for a reinforced concrete bare frame, un-reinforced brick masonry infilled frames and frames with combinations of shear walls. The study is carried out on five different cases by providing infill walls and shear walls at various
locations in different Staad models being prepared and analyzed. Initially, the comparison of response parameter of the reinforced concrete building with bare frames and masonry infilled frames are made. Infill Stiffness has been modeled using an equivalent diagonal strut approach. Struts acting in compression against infill walls have been taken in consideration for the outer frames of the building. Further, the analysis is carried out is to determine that by providing shear walls at the particular location by how much amount the storey drift and column shear can be reduced. The shear walls are modeled as RC structural plate elements divided into small grids and are installed from foundation level to the full building height at their respective positions in the structure. The various cases of the building were modeled and analyzed for seismic requirements as per Indian seismic code IS : 1893-2002(Part I).
