摘要

摘要: 通过 2 3根粘贴碳纤维布 (CFRP)钢筋混凝土偏压柱及其对比柱在单调荷载作用下的试验研究 ,比较分析了CFRP加固前后偏压柱的承载力、延性及破坏形态。试验结果表明 ,在偏压柱的受拉面纵向粘贴CFRP可以较大地提高偏压柱的承载力 ,但不能改善柱子的延性 ;横向粘贴CFRP能显著地改善偏压柱的延性 ,柱的承载力也有所提高 ;纵、横向混合粘贴CFRP的加固效果最好 ,柱的承载力和延性均有较大提高。此外 ,根据试验结果的分析 ,提出了纵向粘贴CFRP的偏压柱的正截面承载力计算方法 ,计算结果与试验结果吻合良好。

Abstract: By experiment of 23 reinforced concrete columns under eccentric loads,the strength capacity,ductility and failure modes of the columns with and without CFRP bonding are compared and analyzed.Experimental results indicate that when bounded only with longitudinal CFRP,the strength capacity of the columns increased but the ductility of the columns decreased slightly.When strengthened with transverse CFRP,the ductility of the columns improved significantly,and the ultimate strength increased as well.When strengthened by the combined action of the longitudinal and the transverse straps of CFRP,most significant improvement in the strength and the ductility of the columns resulted.On the basis of the experiment,the method of calculating the ultimate strength of eccentrically-loaded columns reinforced by longitudinal CFRP is presented,the calculating results fit well with the experimental data.
