摘要: 根据工程情况，通过对比不同工法玄武岩纤维布(BFRP)加固榫卯节点后的榫卯节点力学性能，探讨不同工法下BFRP加固榫卯节点的抗震性能；主要包括滞回曲线、骨架曲线、强度和刚度退化规律、极限承载力和最大刚度等。试验结果表明，不同工法下BFRP加固榫卯节点的滞回曲线图形明显不同，榫卯节点的极限承载力和最大刚度也有较大幅度差距。

Abstract: In accordance with the conditions of a project, it is compared the mechanical properties of BFRP reinforced mortise-tenon joint of different construction methods, and explored the seismic performance of the said joint, including hysteretic skeleton curve, strength and stiffness degradation rules, ultimate strength and maximum stiffness.The results show that hysteretic curve graph of BFRP reinforced mortise-tenon of different construction methods is obviously different, the ultimate strength and maximum rigidity of the mortise-tenon joint also have a greater difference.
