对 9根玻璃纤维布加固的钢筋混凝土梁和 3根对比梁进行了抗弯性能试验研究 .试验中考虑了配筋率、加固量、剪跨比与混凝土强度等级 4个参数 .试验结果表明 ,经玻璃纤维布加固的钢筋混凝土梁抗弯承载力有显著提高 ;混凝土强度、配筋率、加固量对极限荷载有显著影响 ;剪跨比对加固梁的破坏形态有影响 .根据不同的破坏模式 ,提出了抗弯承载力计算方法 . The flexural properties of 9 reinforced concrete beams reinforced with glass fiber reinforced plastic and 3 comparative beams were studied in this paper.The parameters of reinforcement ratio, reinforcement ratio, shear span ratio and concrete strength grade were taken into account in the experiment.The results showed that, The flexural capacity of reinforced concrete beams strengthened by glass fiber cloth significantly increases; the concrete strength, reinforcement ratio and reinforcement amount have a significant impact on the ultimate load; and the shear span ratio has an impact on the failure mode of reinforced beams. According to different failure modes The calculation method of flexural capacity.
