| 摘 要： | 为研究多自由度基础隔震结构的随机地震响应问题,用多个振型将上部结构展开,针对所得方程的非经典阻尼、非对称质量和非对称刚度情况,采用复模态法进行解耦,获得了以多振型表示的结构地震响应的计算表达式。算例结果表明多自由度基础隔震结构减震效果显著。

| Abstract: | In order to study the random earthquake response of multi-degree structure with base isolation,the upper structure is unfolded through multi-mode.According to the situation that the damping is non-classical damping and the structure is non-symmetry,the complex model method is used to disconnect the equations,and the precise solution of earthquake response expressed by multi-mode is obtained.The example shows that the multi-degree of freedom structure with base isolation can reduce earthquake response obviously. |
