摘　　要：采用GFRP叠层橡胶支座作为结构的隔震支座,同时输入X,Y双向地震波,通过动力时程分析将使用GFRP叠层橡胶支座的基础隔震结构较抗震结构进行对比,分析加速度、剪力、位移的性能变化规律.同时得出输入双向地震波的必要性,为使用GFRP叠层橡胶支座设计的基础隔震结构的推广提供一定依据.The GFRP laminated rubber bearing was used as the isolation bearing of the structure,and the X and Y two-way seismic waves were input at the same time.Through the dynamic time history analysis,the base isolated structure with GFRP laminated rubber bearing was compared with the aseismic structure.The performance change rules of acceleration,shear force and displacement were analyzed.Meanwhile,the necessity of inputting bi-directional seismic waves was obtained,providing a certain basis for the popularization of base isolation structures designed with GFRP laminated rubber bearings.
