随机地震激励下基础隔震结构的复模态解析法
The complex mode methods for analysis of random earthquake response of stuctures with base-isolation
【摘要】 运用复模态方法,系统研究了基础隔震结构在随机地震激励下的响应.由于基础隔震结构运动方程为非经典阻尼和非对称质量、刚度情况,故采用复模态解耦振动方程,得到基础隔震结构的响应解析解.
【Abstract】 The earthquake response and earthquake action of structures with base-isolation is studied systematically in the paper.According to the situation that the motion equation of structures with base-isolation is a non-classical damping,and the mass and rigidity are non-symmetic,the complex mode method is used to disconnect the equations.And then the exact solution of earthquake response is got by using the random earthquake method.
