| 摘 要： | 基于内嵌碳纤维(简称CFRP)筋抗弯加固混凝土梁的试验研究,开展变加固量内嵌CFRP筋加固梁可靠指标计算分析,探讨内嵌CFRP筋加固钢筋混凝土梁的可靠度水平随加固量的变化情况。结果表明:内嵌CFRP筋加固梁能够充分利用CFRP的高强特点,明显提高被加固梁的可靠性,其可靠指标提高幅度最大为79.52%。综合各方面因素分析可知,内嵌2根CFRP筋的加固效果最好。

| Abstract: | Based on the flexural experimental research on RC concrete beams strengthened with NSM CFRP tendons,the reliability index before and after reinforced concrete beams strengthened with the amount of CFRP tendons was studied.The reliability analysis of different amount of RC concrete beams strengthened with NSM CFRP tendons was discussed.The results showed that the reliability index could be enhanced maximally by 79.52%,which not only made full use of the intensity of the CFRP tendons,but also improved observably the reliability of the reinforced beams.The reinforcement effect with two NSM CFRP tendons was better than the others. |
