摘要: 对实际荷载条件下的锈蚀钢筋混凝土梁经碳纤维加固后的耐久性进行研究,分析构件在荷载条件下的各种力学指标和耐久性指标的变化,试验结果表明:采用碳纤维加固混凝土梁可行,加固后的混凝土梁力学指标和耐久性指标都得到了不同程度的提高,但是采取的加固防护形式不同,对混凝土梁的耐久性指标有较大的影响。Abstract: It is carried out a study on the durability of corroded RC beams strengthened by CFRP,it is mainly analysed the changes in all mechanical indexes and durability index of the reinfored members under loading,The experimental result and theoretical analysis show that not only the reliability index of concrete structure,but also the resistance to corrosion can be enhanced inevitably.However there are different results according to different methods of reinforcement.
