Study on the Earthquake Response of a RC Building with Base Isolation
Nitya M | Arathi S [8]
Abstract: Base isolation is an effective method for earthquake resistant design to reduce vibrations transmitted from ground to the structure. The principle of seismic isolation is to introduce flexibility in the structure. In the present study of base isolation, a plus shaped G+6 storey with rubber isolation and friction isolation have been analyzed using SAP 2000 software. The analysis is done using nonlinear seismic Time History data for with and without base isolation condition. Time history analysis has been performed on earthquakes EL Centro, 1940. So in this work the performance of RC building in dynamic are studied with base isolation and the results are compared with the results obtained for building without base isolation. It was observed that base isolation increases the time period of the building & hence correspondingly reduces the base shear.
