摘要通过对3根对比梁和8根加固梁进行了试验研究,结果表明:CFRP布嵌入式加固能有效提高混凝土梁的抗弯承载力,另外,不同初始弯矩作用下加固梁的极限承载力几乎相同。 Experimental research on the flexural behavior of three Reinforced Concrete （RC） beams and eight beams strengthened by NSM CFRP sheets has beening carried out. The results generally indicate that the flexural strength of the repaired beams is increased. And the ultimate strength of RC beams strengthened by NSM CFRP sheets is almost the same under the act of different first moments.
