【摘要】 本文将传递矩阵法的应用范围由结构的固有振动分析推广到频域内的地震反应分析。文中具体给出了弯剪粱结构的单元传递矩阵的频域形式。用这种频域内的传递矩阵，结合离散傅里叶变换，即可求得多自由度弯剪梁体系的地震反应。同样地，可用这种方法计算各种串联多自由度体系在其它动力荷载下的反应。该方法精度良好且比相应的有限元法节省计算机ＣＰＵ时间。更多还原

【Abstract】 The application of transfer matrix method is extended from eigen value analysis of struc-tures to the earthquake response analysis in frequency domain in this paper.In combinationwith Fourier transform,the transfer matrix method in frequency domain can be used to ob-tain the earthquake response of multi-degree bending-shearing systems. The method can alsobe used to compute the system response under other dynamic loads.The method has goodprecision and uses less computer CPU time than the finite element method.更多还原
