摘　　要：从平面杆单元的经典刚度方程出发,在引入基本假定的基础上由严格的数学方法得到了平面杆系结构的统一计算模型.当该模型中的有关参数取特殊值时可直接得到理想的桁架模型和刚性连接模型,而且可用于具有任意半刚性连接和混合结点的一般杆系结构的静力分析.On the basis of the fundamental assumptions for the planar steel structures with semi-rigid connections and the typical stiffness equations of the framed element, the generalized elastic computational model of the planar steel structures, of which the arbitrary connection stiffness can be assumed at the ends of each element, is put forward with mathematical derivations. With the parameters associated with the semi-rigid connections considered in this model taking special values, the model can easily degenerate into two of the idealizations: fully rigid and pinned. The model presented here can also be used in a static analysis of general structures with semi-rigid connections and mixed connections.
