Seismic Evaluation of Multi Storey RC Buildings with and Without Fluid Viscous Dampers
Earthquakes are one of the most destructive of natural hazards. Earthquake occurs due to sudden transient motion of the ground as a result of release of energy in a matter of few seconds. These recent events remind us of the vulnerability of our society to natural hazards. The protection of civil structures, including material content and human occupants is, without doubt, a worldwide priority. The challenge of structural engineers is to develop safer civil structures to better withstand these natural hazards. In the present study reinforced concrete moment resisting frame building of G+20 are considered. The building is considered to be located in the seismic zone (v) and intended for commercial purpose. Model-I Building without dampers, Model-II –Building with dampers. The building of G+20 has been modeled by providing with and without damper providing all parameters using S A P 2 0 0 0 software. Results show that using fluid viscous dampers to building can effectively reduce the building responses by selecting optimum damping coefficient i.e. when the building is connected to the fluid viscous dampers (FVD) can control both displacements and accelerations of the building. Further damper at appropriate locations can significantly reduce the earthquake response.
