| 摘 要： | 通过对典型榫卯连接的力学分析和模型低周反复荷载试验,研究了榫卯的半刚性连接特性和刚度退化的规律。试验得到榫卯连接的弯矩-转角滞回曲线和骨架曲线,并拟合出了榫卯节点恢复力模型。将榫卯连接比拟为变刚度杆单元,理论推导了变刚度和相对柔度之间的关系。结果表明,木结构的榫卯连接刚度随荷载变化而呈非线性变化,刚度在0.3062~23.6054之间变化。研究结果可为木结构古建筑的抗震性能研究和修缮加固提供理论基础。 |

| Abstract: | The typical mortise-tenon joints in historic timber buildings were analyzed in mechanics. The low cyclic reversed loading tests were carried out. The semi-rigid characteristic of the joggle joint and the change rules of stiffness degradation were obtained. The moment-deflection angle hysteretic curves were tested. By simulating the state of mortise-tenon joint with the varied stiffness element, the relation between the varied stiffness and the relative flexibility was found. It is shown that the stiffness change of the mortise-tenon joint is nonlinear from 0.3062 to 23.6054 with the change of load. It may provide information, suggestions and theoretical base for seismic research, protection and maintenance of historic timber buildings. |
