摘　　要：以西安城永宁门箭楼为研究对象,通过对3个带雀替木构架模型在低周水平反复荷载作用下的试验研究,分析了半榫榫卯节点的受力变形特征及其破坏形式,得到了相应的弯矩-转角滞回曲线、骨架曲线、节点特征参数和恢复力模型,确定了半刚性榫卯节点的延性系数范围在1.58~3.99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参考。Taking the Embrasured Watchtower of Yongning Gate（ South Gate） of Xi ＇an City wall as research objects,the low cyclic horizontal loading tests were implemented on three timber frame models. The timber frame nodes＇ characteristics of stressed deformation and failure modes were analyzed. Corresponding moment- rotation hysteresis curves,skeleton curves,characteristic parameters and restoring force model of mortise- tenon joint were obtained. It can be determined that the ductility factors of semi-rigid mortise-tenon joint nodes of the timber frame change from 1. 58 to 3. 99. The research results can provide a reference to seismic performance analysis,protection and maintenance of ancient Chinese timber buildings.
