摘　　要：为了研究混凝土翼板外伸锚固对梁柱端板连接半刚性组合边节点初始转动刚度的影响,运用组件法和弹塑性理论提出了混凝土翼板外伸锚固对梁柱端板连接半刚性组合边节点初始转动刚度影响的计算公式,通过与试验结果对比表明:计算值与试验值吻合较好。因此,该计算公式可用于梁柱端板连接半刚性组合边节点刚性的判断和参数研究。In order to study the effect of the initial stiffness of the semi-rigid composite exterior joint with the Beam-Column end-plate connection on the overhang anchorage for concrete flange slab,the computing formulas are proposed by the component method and the elastic-plastic analysis in this paper.By comparison with the results of experimental result,it’s verified that the method to calculate the initial stiffness of the semi-rigid composite exterior joint with the Beam-Column end-plate connection on the overhang anchorage for concrete flange slab is accurate enough to estimate its rigid behavior and make its parametric study.
