非比例阻尼隔震结构地震响应的实振型分解法 - In view of characteristics of the thick slab , the author suggests using not only the method of the modal decomposition but also time interval analyses and found the moment - shear model
鉴于厚板转换层的受力特性，建议对其除用振型分解法进行计算外，还应用时程分析法进行补充计算，提出了层间弯剪的力学模型。 - The mode superposition method , based on equivalent linearization and forcing decoupling method of non - classical damping matrix of energy dissipation systems , is the just one . at the same time , iterative process will increase computing workload and forcing decoupling method increase error
基于等效线性化的强行解耦振型分解法在一定程度上符合此要求，但此方法存在着迭代计算工作量大、强行解耦增大计算误差的不足。 - 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。
