摘要
在18根简支梁试验基础上,对玻璃纤维布加固钢筋混凝土梁后各种参数对梁极限承载力的影响进行了分析,对不同预加载程度对梁的承载力折减及在线加载效果进行了研究,并提出了二次受力梁的抗剪承载力公式,可供实际工程设计参考.
Based on the experiments of 18 simply supported beams, the influences of various factors on the ultimate load of the reinforced concrete beams strengthened with externally bonded GFRP sheets are analyzed. The reduction of the preloaded beam's ultimate load and the effect of on-line strengthening are researched. The formula for calculating the shear capacity of the preloaded beams is put forward. These experimental results can give the reference to the practical projects.
