摘要(Abstract):

通过 1 1根钢筋混凝土柱 (其中 6根用碳纤维布加固 )在低周反复荷载作用下的试验研究 ,比较分析了用碳纤维布 (CFS)加固前后混凝土柱的破坏形态、极限承载力、滞回曲线和延性系数等。结果表明 ,CFS加固钢筋混凝土柱可以提高柱受剪承载力和延性 ,使其抗震性能得到显著改善 ;CFS加固效果与柱的轴压比和配箍率、CFS粘贴方式和层数等因素有关
Based on the experiment of eleven reinforced concrete columns including six columns strengthened with CFS subjected to lateral cyclic loading, the failure mode, ultimate capacity, hysteretic behavior, ductility factor etc. are compared and analyzed. Experiment results reveal that CFS could significantly increase the shear capacity and ductility capacity of concrete columns, the experiment results also indicate that the effectiveness is related to many factors, such as the axial compression ratio, stirrup ratio of columns, wrap type, layer of CFS, and so on.
