摘　　要：通过对粘贴碳纤维布(CFS)的实心黏土砖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CFS加固前后偏压柱的承载力、延性及破坏形态。试验结果表明,横向粘贴CFS能显著地改善偏压柱的延性,柱的承载力也有所提高。此外,根据试验结果的分析,提出了纵向粘贴CFS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。By experiment of unreinforced masonry （URM） columns under eccentric loads, the strength capacity, ductility and failure modes of the columns with and without CFS bonding are compared and analyzed. Experimental results indicate that when strengthened with transverse CFS, the ductility of the columns improved significantly, and the ultimate strength increased as well. On the basis of the experiment, the method of calculating the ultimate strength of eccentrically 2 loaded columns reinforced by longitudinal CFS is presented, the calculating results fit well with the experimental data.
