ABSTRACT

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.

摘要

通过理论和实验分析研究了纤维增强聚合物 (FRP) 层压橡胶隔离器的性能。通过循环准静态实验分析了FRP橡胶隔振器的有效水平刚度。进行了 1/3 比例振动台试验，以评估 FRP 层压橡胶隔振器在不同现场条件下的地震动下的抗震性能和效率。推导了隔振器的有效水平刚度，并与实验结果进行了比较。试验研究表明，具有诸多优点的FRP层压橡胶支座可应用于建筑结构中，以增强抗震能力。
