摘　　要：在钢-混凝土组合结构中,钢梁与混凝土柱之间常采用单剪板连接方式,单剪板连接节点主要传递梁端的剪力和轴力,并且能够承受一定的弯矩。为了研究钢梁混凝土单剪板连接节点的初始转动刚度,对3个钢梁-钢筋混凝土柱单剪板连接节点进行静力单调加载试验,分析了螺栓直径、螺栓数量、螺栓洞口变形、连接板抗剪和抗弯刚度及预埋件锚筋变形等因素对初始转动刚度的影响,推导了钢梁-钢筋混凝土柱单剪板连接节点的初始转动刚度计算方法,其计算结果与试验结果吻合较好。In the steel-concrete composite structures,single shear plate is usually used to connect the steel beam and concrete column. The single shear plate joint mainly transmits the shear force and axial force at the end of the beam,and it can bear a certain bending moment. In order to investigate the initial rotational stiffness of the joint of the steel beam concrete single shear plate,the static monotonic loading test of 3 steel beams-reinforced concrete column single shear plate joints were carried out. The influence of the diameter and the number of bolts,bolt hole deformation,shear and bending stiffness of the joint plate and the deformation of embedded anchor bars on initial rotational stiffness were discussed. The calculation method of the initial rotational stiffness of single shear plate joint of steel beamreinforced concrete column was derived,and the calculation results were in good agreement with the experimental results.
