摘 要:通过21根碳纤维增强复合材料(CFRP)编织管约束混凝土短柱的准静态轴压试验,研究了CFRP层数、水灰比、试件长径比对混凝土短柱抗压强度和变形性能的影响。结果表明:CFRP编织管约束试件的承载力相比素混凝土试件至少提高了10%;水灰比在一定范围内变化时,对试验结果的影响不大;试件长径比越小,CFRP对最大荷载的提升作用越明显。
Abstract: Through the quasi-static axial compression tests of concrete short columns confined by 21 carbon fiber reinforced composite material(CFRP) braided tubes, the effects of the number of CFRP layer, water-cement ratio, and length-diameter ratio of specimen on the compressive strength and deformation characteristics of concrete short columns were studied. The results show that the bearing capacity of the CFRP tube confined column is at least 10% higher than that of the plain concrete column. The water-cement ratio has little effect on the test results within a certain range. The smaller the length-diameter ratio of the column, the more obvious the increase in the maximum load by CFRP.
