摘要：
Performance of fiber-reinforced polymer (FRP)-laminated rubber isolators has been investigated through theoretical and experimental analyses. Effective horizontal stiffness of FRP rubber isolator is analyzed by the cyclic quasi-static experiment. A 1/3 scale shake table tests have been carried out to assess the seismic behavior and the efficiency of the FRP-laminated rubber isolator under the ground motions in different site conditions. The effective horizontal stiffness of the isolator has been derived which has been compared with the experimental results. Experimental studies have shown that FRP-laminated rubber bearings with many advantages can be applied to building structures to enhance seismic capacity.
