摘　　要：就框剪结构的动力特性问题 ,采用动力凝聚方法把从属自由度缩减到便于求出侧移刚度矩阵 ,从而把原来的框—剪体系转化为带有集中质量的杆件模型 ,由广义JACOBI法求出频率和振型 ,然后针对算例 ,对一般的框—剪体系的简化作了分析 ,取得了很好的效果 。In this thesis,we decress the subordination degree of freedom with condesation technology to get the lateral stiffness matrix from the structure one according to dynamic character analysis of the frame\|shear wall structure.Then we are able to obtain a model in which only some lumped mass are supported by an elastic massless column.In the end,we calculate the natural frequency and the natural period of the system with general JACOBI method while making analysis of simplification of the frame\|shear wall structure.Through the analysis,we obtain excellent results which shall have some important guiding and reference signficance to practical engineering.
