摘　　要：通过对无机胶粘贴碳纤维布混凝土柱与有机胶粘贴碳纤维布加固的混凝土柱以及未加固的混凝土柱进行轴压试验,对比各柱的破坏形态、抗压强度、变形能力和应力-应变曲线。结果表明:无机胶粘贴碳纤维布加固的混凝土柱可以取得较高的抗压强度和较好的变形能力。通过对试验数据进行回归分析,提出无机胶粘贴碳纤维布约束混凝土的抗压强度、极限压应变计算式和本构关系模型。By conducting axial compression tests on unstrengthened concrete columns and carbon fibre reinforced polymer（ CFRP） strengthened concrete columns whose CFRP sheets were bonded with inorganic or organic adhesive,the failure modes,compressive strength,deformation capacity and stress-strain curves of the columns were analyzed.The results indicated that the concrete columns strengthened with CFRP sheets bonded with inorganic adhesive could obtain high compressive strength and fairly good deformability. Based on the regression analysis,the formulas of compressive strength and ultimate compressive strain were proposed,as well as the constitutive model of concrete confined by CFRP sheets bonded with inorganic adhesive.
