摘　　要：采用了一种计算轻钢结构梁柱半刚性端板连接转动变形的方法,通过与有限元软件计算的结果比较得到验证,该方法不但能够较好地计算端板连接的整体转动变形特性,包括初始转动刚度和弯矩—转角(M—θ)全过程曲线,而且能够较好分析计算其转动变形的各种来源,包括节点域剪切变形、螺栓伸长、端板和柱翼缘弯曲变形等,从而能够提供弯矩—剪切转角(M—θS)和弯矩-缝隙转角(M—eθp)曲线,为准确分析端板连接的细部转动变形特性提供了可靠依据,同时也为我国轻钢结构设计规程关于节点转动变形的具体设计计算方法提供了有益补充.A new method to calculate rotational deformation of light steel structure beam-tocolumn semi-rigid end-plate connections has been proposed in this paper. It has been verified by the relevant calculation results of the finite element software that this method can calculate the integral rotational behavior of end-plate connections, including the initial rotational stiffness and the moment-rotation（M-θ）curve accurately. Further more, it can analyze and calculate each source of joint rotational deformation including the shear deformation of the panel zone, the bolt extension, the bending deformation of the end-plate and column flange, etc. As a result, this method can provide the moment-shear rotation （M-θs）curve and moment-gap rotation （M-θep） curve, which provides reliable calculational basis for analyzing the detailed rotational behavior of end-plate connections. This method presents a supplement to the light steel structure design code of our country.
