摘　　要：锈蚀钢筋混凝土梁出现锈胀裂缝后即进入裂缝修复期,在裂缝修复期间锈蚀梁仍然需要必要的安全储备。分析锈蚀钢筋混凝土梁受力机理的基础上,通过锈蚀钢筋应变滞后比,合理考虑锈蚀钢筋与混凝土的协同工作性能,提出了更合理的锈蚀钢筋混凝土梁的剩余抗弯承载力评估方法。When the expansion cracks occur,the Corroded reinforced concrete beam Repair period.During the repair of cracks,the corroded beams still need the necessary safety reserves.Based on the analysis of corroded reinforced concrete beams on the basis of the mechanism,than through the corroded strain hysteresis,by the reasonable consideration of the work performance between the corroded steel bars and concrete,the reasonable Evaluation on the remaining flexural capacity of corroded RC beams was proposed.
