A Study on Seismic Response of Multistoried Buildings with Shear Walls and Fluid Viscous Dampers using ETABS

Earthquake is the one of the significant disaster that can affect the performance and safety of any RCC building to the highest level possible. Hence there is imminent need to arrest the damage by seismic forces and make the RCC structures to withstand for earthquakes. Many alternate retrofitting techniques have emerged which can alter the response of RCC structures in resisting the seismic forces. Retrofitting the existing structures with dampers or providing shear wall as an integral part of the structure was among them. Dampers have a wide range of advantages like they can be erected in an easy way, cost effective and can be installed in the desired orientation such that the strength and stiffness requirements will be met. The present work deals with comparison of response of RC framed structures with fluid viscous dampers and shear walls. For this study, a reinforced concrete framed building (G + 9) was modeled and analyzed in three parts 1) Model without shear wall and Fluid viscous damper (Base model) 2) Model with shear wall 3) Model with Fluid viscous dampers. The response of the structure for the above conditions have been evaluated using E-Tabs 2015 for seismic forces for different seismic zones. In this study parameters like Lateral displacement, Storey shear and Storey drift have been carefully evaluated and were used to compare the seismic response of RCC structures with fluid viscous dampers and shear walls.
