摘要
根据梁柱外伸式端板连接节点的简化学模型 ,提出一种用已知节点尺寸来预测其弯矩转角关系的非线性数学模型 ,在对节点的各种可能破坏形式和初始位移做了理论分析后 ,给出了计算模型参数极限弯矩和初始转动刚度的方法 。
The moment and rotation curves for extended end?plate connection of a beam?column are studied in the paper.It is regarded that this kind of connection is good for moment resistance frames. Based on a mechanical model of extended end?plate connections, a kind of moment and rotation curves is proposed.All possible failure forms and initial displacements of the connection are discussed in detail.The formulas for the ultimate moment and the rotational initial stiffness of the connection are presented.The proposed formula is compared with that of the theoretical one;it is in good agreement in the elastic range.
