| 摘 要： | 对5根混凝土梁进行抗弯试验研究,包括1根对比梁、2根无损伤加固梁和2根损伤加固梁,研究了在开槽数目不同及加固条件不同的情况下,内嵌碳纤维板条钢筋混凝土梁的抗弯性能.研究发现,二开槽加固梁比三开槽加固梁的承载能力有所提高,损伤加固梁的承载能力略高于无损伤加固梁,加固梁的裂缝较对比梁的裂缝宽度小,延伸缓慢,分布更为均匀.

| Abstract: | In order to research the flexural behavior of RC beams strengthened with near-surface mounted （NSM） CFRP laminates,one reference beam,two strengthened undamaged beams and two strengthened damaged beams were studied by experiments.Considering different grooves and different strengthening condition,the flexural behavior of embedded carbon fiber strip of reinforced concrete beams were investigated.The results indicate that the bearing-capacity of strengthened RC beams with two grooves is higher than that of beams with three grooves,and the bearing capacity of damaged strengthening beams is better than that of undamaged strengthening beams.Compared with the referenced beam,the cracks in the strengthened beams are narrower,less slowly propagated,and better equally distributed. |
