求解非比例阻尼体系复模态的实模态摄动法
Earthquake and wind ) , because of the damping matrixes of the two structures " motion equations are both non - classical , the dynamic equation ca n ' t be decoupled by the traditional real - mode analysis ( the mode - superposition method ) . though , in this thesis the complex - mode analysis is used to solve the stationary and non - stationary random earthquake response of structures and their analytic expressions are got . on the basis of these expressions , the optimal parameters of the two structures " isolation & seismic decrease equipment are analyzed
目前，基础隔震结构、 “加层减震” ( tmd减震)结构正逐步应用于工程实际，由于这两种结构在动力荷载(如地震、风)作用下动力方程中的阻尼矩阵为非经典情形，传统的实模态分析方法(振型分解法)不能使动力方程解耦，因此本文运用复模态分析方法求得了结构在平稳和非平稳随机地震激励下结构随机地震响应的解析表达式，在此基础上进行了基础隔震和tmd减震装置参数的优化分析。
