Behavior of Coupled Shear Wall with Damper in High Rise Building

The reinforced concrete shear wall is used in seismic prone zone to counter lateral forces & they are most appropriate structural component in high rise building. It provide the stiffness and strength during earthquake but the coupled shear wall gives more stiffness and strength and it is outstanding structure to resist gravity loads. The behavior of coupled shear wall is regulated by the coupling beam. The outcome of the above structure can be increased by providing a damper. Here a viscous damper has been used for the analysis along with the coupled shear wall. This study mainly focuses on the analysis and design of coupled shear wall with and without damper. Time history method is used for dynamic analysis. Parameters like storey drift, storey displacement, storey stiffness, storey shear and base shear of a structure are determined by using ETABS software. The comparative study of the above parameters for the models that is bare frame, shear wall, coupled shear wall without damper and coupled shear wall with damper have also been studied. In this study we found the coupled shear wall with damper reduces the response of structure like storey drift and displacement etc and increase the storey stiffness of the structure. The scope of present work is to study the effect of seismic loading on placement of coupled shear wall in building at different position of damper.
