碳纤维布和角钢复合加固损伤混凝土柱抗震性能理论研究

Seismic performance of the injury RC column strengthened by angle steels and CFRP sheets

基于已有的碳纤维布和角钢复合加固损伤混凝土柱水平低周反复荷载试验结果,推导了碳纤维布和角钢复合加固损伤钢筋混凝土柱的正截面承载力计算公式。经试算,与试验结果符合良好。进行了计算公式的可靠度分析,表明本文推导的计算公式满足可靠度要求,并建议了经济的角钢加固肢长,可供加固设计参考。

Based on the experiments under low-cyclic and repeated load for injury RC columns strengthened by CFRP sheets and angle steels, the flexural capacity formula was derived. The calculation results matched the experimental results well and the formula fulfilled the requirements of reliability. The economic limb length of strengthened angle steel was suggested for the design reference.
