对历史木结构建筑中典型的榫卯结构进行了力学分析。进行了低循环反向载荷试验。得到了铰接接头的半刚性特性和刚度退化的变化规律。测试了力矩-偏转角滞后曲线。通过对变刚度单元的榫卯连接状态进行模拟，发现了变刚度与相对柔度之间的关系。结果表明，榫卯结构的刚度随载荷的变化呈非线性变化，从0.3062到23.6054。可为历史木结构建筑的抗震研究、保护和维护提供信息、建议和理论依据。
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.
