Study on Seismic Performance of Mortise-tenon Reinforcement Joints in Chuan-dou Style Timber Structure
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.
