摘　　要：采用杆系模型形成结构的总刚矩阵,分析时考虑了梁、柱的弯曲、剪切、轴向变形以及节点域的剪切变形;经过静力缩聚将其化为质点串模型,然后结合层模型的一些特点,得出等效层间剪切刚度,最后利用层间剪切模型的简化二阶分析方法得到了考虑二阶效应及节点剪切变形的层间剪切模型总刚矩阵。In this paper, the global stiffness matrix is formed by using member model based on bend deformation, shear deformation, axial deformation of beams and columns and shear deformation of panel zone of joint. The structure is simplified as a series of mass points by static condensation method. Then, we deduced equivalent story shear stiffness taking advantage of some features of the model. At last, the global stiffness matrix of story shear model with second order effect and shear deformation of panel zone of joint is deduced by using simplified second order analysis method of story shear model.
