摘要
通过力法原理对碳纤维布加固混凝土梁的机理进行了探讨,结果表明钢筋混凝土梁在外贴碳纤维布加固钢筋混凝土结构时,改善了结构的受力状态,提高了结构的整体刚度和原有结构的承载能力;分析了爆炸荷载作用下钢筋混凝土构件的破坏形态和影响因素,得出了钢筋混凝土梁抗爆加固的措施。
The mechanical principle of the strengthened RC beams with CFRPs are discussed by the principle of force method.The results show that sticking CFRPs to strengthen the RC structure can improve the RC structure performance under loading and upgrade the total stiffness and the load-bearing strength of the RC structure.The failure mode and influencing factors of RC beams under blast loading are analyzed.And the antiknock and strengthening methods of RC beams are obtained.
