摘　　要：首先利用分解法建立了梁柱螺栓端板连接节点的力学模型 ,然后基于梁板理论给出了节点初始转动刚度的解析公式。公式综合考虑了端板变形、柱翼缘以及螺栓对初始转动刚度的贡献 ,可方便地推广于平端板和外伸加劲端板连接初始转动刚度的计算。公式计算结果和试验结果以及有限元分析结果作了对比 ,吻合较好。同时给出了便于工程设计的简化公式。Based on the beam and plate theory, an analytical model to describe the initial stiffness of end-plate steel connections is presented. Explicit formulae are obtained for three types of end-plate connections, i.e., flush, extended unstiffened and extended stiffened, in which the effects of deformation of column flange, end-plate and bolts are taken into account. The influence of the end-plate thickness and the connection type on the initial stiffness is discussed. The results agree well with the FEM and experiment results.The approximate expressions of the explicit formulae are suggested.
