Response Analysis of Mid-Story Fixed Base and Base Isolated Unsymmetrical Building under Seismic Action

Abstract

Base isolation is design approach, which reduces the transmission of accelerations due to ground motion into structure. The seismic isolation reduces the earthquake forces by increasing period of vibration of the structure. In this paper investigation regarding seismic response of base-isolated (BI) mid-story unsymmetrical reinforced concrete buildings and fixed-base (FB) building will be performed with a similar structural system above the ground.
