摘　　要：研究了体外粘贴碳纤维增强复合材料CFRP(Carbon Fiber Reinforced Polymer)加固钢筋混凝土开孔平板的受力性能,通过5块开孔平板的加固试验,从破坏形态、开裂荷载、极限荷载和弯曲变形等方面分析构件的加固效果,研究粘贴层数、开孔尺寸和开孔位置等因素对构件加固效果的影响。试验结果表明,经外贴CFRP加固后,钢筋混凝土开孔平板的极限承载力、弯曲变形能力均得到明显提高,构件的抗裂性能也有一定程度的提高。The mechanical behaviors of RC plates with opening strengthened by the CFRP（Carbon Fiber Reinforced Polymer） are studied, The strengthening effects are analyzed by comparing the cracking load, the ultimate load,the flexural deformation and the failure type of these members. The main parameters considered are the thickness of CFRP,the size and the location of the opening. The results indicate that the ultimate capacity can be improved significantly as well as the ultimate deformation and the cracking load can also be increased.
