【摘要】 采用串联刚片系模型对隔震结构的多维地震响应进行分析。基于非线性时程分析方法,利用SAP2000有限元软件探讨了双向水平地震输入时不对称多塔楼基础隔震、层间隔震和抗震结构的地震响应特性,比较了结构自振周期、结构位移、结构加速度和剪力等的特点。结果表明,采用隔震技术可以显著地降低地震的破坏作用,而层间隔震对减小多塔楼结构体系的扭转作用更为明显。更多还原

【Abstract】 In this paper,rigid panel model is used to analysis the multi-dimensional seismic response of isolated structure. Based on nonlinear time-history analysis method,the seismic response of base isolation,layer isolation and seismic structure of natural period,displacement,structrual acceleration,shear was discussed by using finite element software SAP2000 under the two-directional horizontal earthquake. The result show that the structure using isolation technology can significantly reduce the destructive effects of earthquakes.Layer isolation reduced more significantly torsional vibration response.更多还原
