摘　　要：对钢筋混凝土梁进行了粘贴碳纤维布加固的正截面受弯承载能力试验分析研究。试验结果表明,碳纤维布可明显提高梁的正截面受弯承载截力。同时对试验结果进行了分析,提出了碳纤维布加固钢筋混凝土梁正截面受弯承载力影响因素及新的计算方法,便于实际工程使用。A series of reinaforced concrete beams strengthened ha flexure with carbon fiber-reinforced polymer laminates were tested and studied. The test results showed that the carbon fiber sheets reinforcement could highly inacrease the flexural bearing capacity of the concrete beams. Based on the testinag results, the load-deformation process, flexural failure characteristics and the effect of various parameters on their behavior are all discussed. Furthermore, a new calculatting method for the ultimate flexural bearnig capacity of reinforced concrete beams strengthened with CFRP is put forward for referential use ha the practical enghaeering.
