Reinforcement corrosion is one of the main reasons for the deterioration of reinforced concrete (RC) structure. Corroded RC beam-column joint experiences large deformations under the earthquake, which results in the deterioration of the seismic behavior. Although researches on the uncorroded joints strengthened with fiber-reinforced polymer (FRP) sheets have been conducted, investigations on the corroded RC beam-column joints repaired with basalt FRP (BFRP) sheets are relatively limited. In present research, seven interior beam-column joints were tested under the cyclic loading, including one reference specimen, three specimens with different corrosion rates, and three corroded specimens repaired with BFRP sheets. The seismic behaviors in terms of crack pattern, failure mode, hysteretic curve, load bearing capacity, deformation capacity, energy dissipation, and stiffness degradation were discussed. Results obtained from the test showed that: (1) the seismic behaviors of corroded beam-column joints were effectively improved by the utilization of BFRP sheets; (2) the spalling, and crushing of concrete, as well as the buckling of stirrups were delayed by the utilization of BFRP sheets; (3) the load bearing capacity, ultimate displacement, and energy dissipation capacity of corroded beam-column joints were effectively increased, and the stiffness was fully recovered to that of uncorroded joint by repairing with BFRP sheets; (4) the bond behavior between corroded bars and concrete or strains of corroded bars in beam-column joints were improved or decreased after repairing with BFRP sheets.

钢筋锈蚀是钢筋混凝土（RC）结构劣化的主要原因之一。锈蚀的钢筋混凝土梁柱节点在地震作用下发生较大变形，导致抗震性能恶化。尽管已经对纤维增强聚合物（FRP）板加固的未腐蚀节点进行了研究，但对玄武岩FRP（BFRP）板修复的钢筋混凝土梁柱节点的研究相对有限。在目前的研究中，在循环载荷下测试了七个内部梁柱节点，包括一个参考试样，三个不同腐蚀速率的试样和三个用 BFRP 板修复的腐蚀试样。从裂纹模式、破坏模式、滞后曲线、承载能力、变形能力、讨论了能量耗散和刚度退化。试验结果表明：（1）BFRP片材的使用有效改善了锈蚀梁柱节点的抗震性能；(2) BFRP板的使用延迟了混凝土的剥落、压碎和箍筋的屈曲；(3) 锈蚀梁柱节点承载能力、极限位移和耗能能力有效提高，通过BFRP板修复，其刚度完全恢复到未锈蚀节点；(4) 用BFRP板修补后，锈蚀钢筋与混凝土的粘结性能或梁柱节点锈蚀钢筋的应变得到改善或降低。(1) BFRP片材的使用有效改善了锈蚀梁柱节点的抗震性能；(2) BFRP板的使用延迟了混凝土的剥落、压碎和箍筋的屈曲；(3) 锈蚀梁柱节点承载能力、极限位移和耗能能力有效提高，通过BFRP板修复，其刚度完全恢复到未锈蚀节点；(4) 用BFRP板修补后，锈蚀钢筋与混凝土的粘结性能或梁柱节点锈蚀钢筋的应变得到改善或降低。(1) BFRP片材的使用有效改善了锈蚀梁柱节点的抗震性能；(2) BFRP板的使用延迟了混凝土的剥落、压碎和箍筋的屈曲；(3) 锈蚀梁柱节点承载能力、极限位移和耗能能力有效提高，通过BFRP板修复，其刚度完全恢复到未锈蚀节点；(4) 用BFRP板修补后，锈蚀钢筋与混凝土的粘结性能或梁柱节点锈蚀钢筋的应变得到改善或降低。以及由于使用 BFRP 板而延迟了箍筋的屈曲；(3) 锈蚀梁柱节点承载能力、极限位移和耗能能力有效提高，通过BFRP板修复，其刚度完全恢复到未锈蚀节点；(4) 用BFRP板修补后，锈蚀钢筋与混凝土的粘结性能或梁柱节点锈蚀钢筋的应变得到改善或降低。以及由于使用 BFRP 板而延迟了箍筋的屈曲；(3) 锈蚀梁柱节点承载能力、极限位移和耗能能力有效提高，通过BFRP板修复，其刚度完全恢复到未锈蚀节点；(4) 用BFRP板修复后，锈蚀钢筋与混凝土的粘结性能或梁柱节点锈蚀钢筋应变得到改善或降低。
