摘要

选取西南民居常见穿斗式木结构典型的直榫型边节点，采用穿木销和穿钢销加固方案，通过单调和低周往复加载足尺试验，对比加固方法对直榫边节点抗震性能的影响。结果表明：相比未加固节点，两种加固节点的破坏程度均有所降低，且有效抑制拔榫现象；穿木销和穿钢销加固节点的初始刚度分别提高了50%和75%，屈服弯矩分别提高了45%和73%，极限弯矩分别提高了27%和69%，耗能能力分别提高了200%和69%。两种方法均有效提高了穿斗式木结构直榫边节点的抗震性能。

Abstract

In this study, the straight tenon-type edge joint was selected, which was the common typical joint in chuan-dou style timber structure of southwestern residential buildings in China. The reinforcement schemes were adopted, which including wood-pin and steel-pin. And the influence of two reinforcement methods on the seismic resistance of straight joints was compared, through the monotonic loading and low-cycle reversed loading full-scale tests. The results showed that the damage degree of the two reinforced joints were reduced, and could effectively inhibit the tenon pulling occurrences, compared with the unreinforced joints. Using wood-pin and steel-pin reinforcement, the initial stiffness of the joints was increased by 50% and 75%, the yield bending moment was increased by 45% and 73%, the moment-resisting capacity was increased by 27% and 69%, and the dissipated energy was increased by 200% and 69%, respectively. In conclusion, both methods effectively improved the seismic performance of mortise-tenon joints in chuan-dou style timber structure.
