摘　　要：采用HBTA2 0程序 ,对我国首栋橡胶垫隔震结构进行双向地震波作用下的弹塑性动力分析。分析结果表明 ,隔震装置的水平变形和耗能能力可以大大减轻地震对结构的影响。最后 。Elasto plastic dynamic analysis for the first structure with rubber bearings base isolation system in China is performed by the program HBTA2 0. The structure is assumed to be under bidirectional earthquake waves.According to the results,the seismic response of the structure is significantly reduced by the distortion and energy dissipation ability of the base isolation system.At last,some suggestions are offered on the dynamic analysis and application of structures with rubber bearings base isolation system.
