Abstract:

The seismic response of a single-story symmetric building with laminated rubber bearing(LRB) is investigated. The comparative performance of laminated rubber bearing isolation investigated for single storey symmetric building under selected past earthquake ground motions. The seismic response is obtained by numerically solving the governing equations of motion using the state-space solution. The behavior of LRB and fixed base structure is studied through various response parameters such as floor acceleration, floor relative displacement, mass ratio, isolator displacement, and isolator force. It is observed that the LRB base isolated system is quite effective in reducing various seismic responses.
