摘　　要：通过对7组粘贴玻璃纤维布(GFRP)的实心黏土砖轴心受压短柱及1组对比柱在单调荷载作用下的试验研究,比较分析了不同长细比和不同FRP加固量等参数对加固砖柱的承载力、延性和破坏形态的影响。试验表明:横向粘贴GFRP布能有效地提高轴心受压短柱的承载力,柱的延性得到显著改善。Through single load testing to 7 groups of solid clay brick masonry column strengthened with GFRP sheet,analyzed that the effects of different length/width ratio,the amount of FRP and other parameters to the heating capacity,ductility,and failure mode of the strengthened column.The test shows that the transversely strengthened GFRP sheet effectively raised the beating capacity of the short column under axial compression and the ductility of the column improved well too.
