| 摘 要： | 采用分阶段连续化模型 ,在考虑了楼板处的集中质量和墙体的分布质量后 ,用传递矩阵法分析多阶变截面框架 -剪力墙结构的自由振动 ,导出了结构的频率方程 ,进而求出了结构的前几阶自振频率和相应的振型。提出的方法也可用于基底隔震结构的分析以及考虑结构与土体动力相互作用的影响时的分析

| Abstract: | A piecewise continuum model for the free vibration of the frame-shear wall structures with varying section was established by considering of the concentrated mass of floors and the distributed mass of walls.The frequency equations of the structures were derived by the transfer matrix method.The structural free vibration frequencies and shapes were determined.This method in also suitable to the analysis of the base isolator structures and the structures considering the dynamic reaction between structure and soil. |
