Effect of Soil-Structure Interaction on Seismic Performance of RC Framed Building with Viscous Wall Dampers
During earthquake, the structure deform beyond the elastic limit and remain intact only due to their inability to deform in-elastically. Therefore most of the earthquake force is absorbed by the RC Framed structure which leads to the damage of the structure. So, to absorb the earthquake force during the earthquake, energy dissipating devices are used. In this study Viscous wall dampers are used as energy dissipating devices for the RC framed structure. The viscous wall dampers are modelled in the finite element software SAP 2000. Non-linear dynamic analysis with Soil Structure Interaction is done for a 15-storey building with Piled-Raft foundation. Four different configuration (placement) of the viscous wall dampers is used in the RC frame building and four different earthquake data is used to find the performance of the viscous wall dampers. The Performance of the VWD (Viscous Wall Damper) is compared with considering soil-structure interaction (SSI) and with the fixed base. The seismic performance of the RC building with and without viscous wall dampers are also compared. It is found that the displacement, inter-storey drift and acceleration and base shear is increased. Considering SSI for the analysis of the VWD, it has been found that displacement and inter-storey drift increases in comparison with the fixed base. So, SSI should be considered during the analysis of the RC framed structure with viscous wall dampers.
