粘贴BFRP布约束钢筋混凝土柱轴心抗压试验研究
Axial compression test on reinforced concrete columns bound
摘要
Abstract
In order to study the failure characteristics and mechanical properties of reinforced concrete columns with different FRP types and layers, a comparative axial compression test on reinforced concrete columns,including 21 circular reinforced concrete columns in which 9 columns are constrained with BFRP and 9 columns with CFRP, 3 others are not wrapped, was conducted.In the test, the lateral strains, longitudinal strains and maximum bearing capacities of the columns were analyzed.The test results show that the bearing capacities of the concrete columns reinforced with two kinds of fiber sheets are improved significantly, the bearing capacity of columns with CFRP is higher than that with BFRP although their difference is small.At the same time, the ductility increases with the strain of columns with CFRP is larger than that with BFRP.The reinforcement effect of the columns with more layers is better than that with less layers.The study concludes that the mechanical properties of the concrete columns reinforced with fiber cloth are enhanced significantly.关键词
