摘　　要：计算了平面率并联多质点系结构在竖向地震作用下的竖向刚度矩阵。从平面率并联多质点系结构的总刚度矩阵中，采用静力凝聚法，消去竖向力和竖向位移与其它广义力和广义位移之间的耦联关系，得出框架结构在竖向地震作用下考虑水平梁和节点转角影响的竖向刚度矩阵。This article calculated the vertical stiffness matrix of plane frame structures subjected to vertical earthquake action. From the global stiffness matrix of plane frame, condensing the static force and eliminating the coupling of vertical force and displacement and other broad sense force and displacement, obtained the vertical stiffness matrix of plane frame structures subjected to vertical earthquake action considering the influence of horizontal girds and nodal. 
