摘　　要：对传统木结构典型的榫卯节点木框架和砖填充墙榫卯节点木框架的低周反复抗震性能进行了对比试验。在试验基础上对比分析了两个试件的破坏模式、滞回曲线、骨架曲线、刚度退化曲线、耗能能力和应变变化。研究表明,砖填充墙榫卯节点木框架正向推时的抗侧承载力、刚度和耗能能力显著提高,反向拉时与对比木框架基本相当;对砖填充墙榫卯节点木框架进行抗震鉴定和加固时,应考虑砖填充墙的影响。Comparison tests on low cyclic reversed seismic performance of the typical mortise-tenon joint wood frame and the mortise-tenon joint wood frame with brick masonry infilled wall of traditional wood structures were carried out. The failure mode, hysteresis loop, skeleton curve, stiffness degeneration curve, energy dissipation capacity and strain change of the two specimens were analyzed based on the tests. The test results show that the mortise-tenon joint wood frame with brick masonry infilled wall has higher lateral load carrying capacity, stiffness and energy dissipation capacity are better than those of the comparison wood frame when the push force is loaded, but the capacity is similar when the pull force is loaded. The seismic evaluation and strengthening of the mortise-tenon joint wood frame with brick masonry infilled wall should take the effect of brick masonry infilled wall into consideration.
