摘要
基于本课题组多年的研究实践,并通过参考国内外的相关研究成果,对碳纤维布加固钢筋混凝土柱抗剪承载力的试验研究成果进行了总结,分析了各种因素对加固后钢筋混凝土柱抗剪承载力的影响。根据18根碳纤维布加固钢筋混凝土柱的抗剪试验资料,应用灰色系统理论,对抗剪承载力及其影响因素进行了关联度分析。分析结果表明,对抗剪承载力影响最大的因子是混凝土抗拉强度,其次是CFRP的抗拉强度、剪跨比、轴压比,影响最小的因子是CFRP配纤率。
Based on the experiment and research practice of my group, the achievements on the shear strength of reinforced concrete columns strengthened with carbon fiber reinforced plastic are summarized through the research details home and abroad. The effect of each factor is analyzed. The factors affecting the shear strength of these 18 hybrid columns are analyzed by grey system theory. The analysis result indicates that the influence factor on the shear strength is reduced in turn with strength of concrete, tensile strength of CFRP, shear-span/ depth ratio, axial compression ratio and amount ratio of CFRP to confined concrete.
