摘　　要：随着新材料的不断出现,新的建筑物加固方法也不断推出,纤维增强塑料(FRP)在土木工程领域的应用就是一例。本文进行了17个(六组)玻璃纤维(GFRP)片材等间距包裹加固砖砌体柱和六个(二组)对比砖柱的轴压试验。试验结果表明:这种加固方式能在不同程度提高砖柱承载力的同时,还能十分有效提高砖柱的极限应变,对提高砖柱的抗压刚度与砖柱的延性发挥了很好的作用。With the development of new materials,the new ways of strengthening for building are also created constantly,and the application of FRP in the field of civil engineering is a case in point.Seventeen（six groups） brick masonry columns wrapped by equal interval GFRP sheets and six（two groups） brick masonry columns for comparison were tested under axial compression.The experiment results indicate that GFRP sheets can obviously enhance the ultimate axial compression strength,the strain peak value of brick masonry columns,and also increase the compressive stiffness and ductility of brick masonry columns.
