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。
The axial compression tests were carried out on the concrete columns reinforced with carbon fiber cloth and the organic adhesive carbon fiber cloth reinforced concrete columns and the unconfined concrete columns to compare the failure modes, compressive strength, deformability and stress-strain curves . The results show that the compressive strength and the deformation ability of concrete columns reinforced with inorganic adhesive bonded carbon fiber sheets can be obtained. Through the regression analysis of the experimental data, the compressive strength, the formula of ultimate compressive strain and the constitutive model of the confined concrete with inorganic adhesive bonded carbon fiber cloth are proposed.
