| 摘 要： | 在12根梁的试验基础上,对碳纤维布加固高强钢筋混凝土梁后的受弯破坏特征及对梁的极限承载力、刚度等的影响进行了研究与分析.试验中考虑了纵筋配筋率、加固量与加固方式、锚固情况、粘结长度四个变化参数.试验结果表明,使用碳纤维布加固的高强混凝土梁抗弯承载力提高较多,加固效果明显.

| Abstract: | Based on the test of twelve beams, the characteristics of flexural failure, the ultimate strength and the stiffness of high- strength reinforced concrete beams strengthened with externally bonded carbon fiber reinforced polymer sheets are studied and analyzed. Four parameters of this experiment program including the reinforcement ratio, the number of CFRP sheets, different strengthening methods and the bonding length are taken into account. It is shown that the application of CFRP sheets can increase the ultimate flexural capacity evidently. |
