本文对多层弹性隔震支座的机械特性进行了实验分析，其中增强元件（通常是钢板）被纤维增强材料取代。纤维增强弹性体隔振器 (FREI) 与钢增强弹性体隔振器 (SREI) 相比，钢增强弹性体隔振器 (SREI) 被假定为在延伸和弯曲方面都是刚性的，而纤维增强弹性体隔离器 (FREI) 被假定为在延伸方面是柔性的，但完全缺乏弯曲刚度。 FREI 的设计和制造是为了评估隔震性能。通过实验来评估和比较纤维增强材料与钢增强材料的性能，以及不同种类纤维增强材料之间的性能差异。实验表明，在隔振器的水平刚度和垂直刚度方面，FREI 的性能优于 SREI。因此，可以生成与 SREI 行为相匹配的 FREI。因此，FREI 可以通过低成本制造和轻型安装取代传统的 SREI 进行隔震。
In this paper an experimental analysis is presented for the mechanical characteristics of multi-layer elastomeric isolation bearings where the reinforcing element—normally steel plates—are replaced by a fiber reinforcement. The fiber reinforced elastomeric isolator (FREI), in contrast to the steel reinforced elastomeric isolator (SREI) which is assumed to be rigid both in extension and flexure, is assumed to be flexible in extension, but completely lacking flexural rigidity. The FREI is designed and fabricated for evaluation of the performance on seismic isolation. Experiments are carried out to evaluate and compare the performances of fiber reinforcement with performance of steel reinforcement, and the differences in performance among different kinds of fiber reinforcements. From the experiments, the performance of the FREI is shown to be superior to that of the SREI in view of horizontal stiffness and vertical stiffness of the isolator. Therefore, it is possible to produce an FREI that matches the behavior of an SREI. Consequently, the FREI could replace the conventional SREI for seismic isolation with low-cost manufacturing and lightweight installation.
