摘　　要：根据钢框架梁柱外伸端板连接节点的简化力学模型 ,提出一种用已知节点尺寸来预测其 M-θr关系的非线性数学模型 ,模型中的主要参数是节点初始转动刚度和极限承载力。在对节点的初始位移和极限承载力进行力学分析后 ,给出了计算初始转动刚度和极限承载力的方法。最后将提出建议计算公式与试验结果进行比较 。Based on the simplified mechanical model of steel frame beam to column extended end plate connections, a nonlinear mathematic model to predict the M θ r relations was proposed by use of the known sizes of the connections in this paper. The major parameters of the model were the initial rotational stiffness and the bearing capacity. After the mechanical analysis about the initial deformation and the bearing capacity of the connections, formulas of calculating the initial rotational stiffness and the bearing capacity were proposed. Compared with the test results, the methods to calculate the initial rotational stiffness and to calculate the bearing capacity were testified to be true at the end of this paper.
