FRP加固钢筋混凝土约束梁抗剪性能试验研究(Ⅰ)——U形竖向粘贴加固

Study on performance of the restrained reinforced concrete beams strengthened by FRP(Ⅰ)——wrapped by U-jacket

在8根梁试验的基础上,研究了T形截面约束梁采用U形竖向粘贴CFRP和GFRP进行抗剪加固时,梁的破坏特征及抗剪承载力,分析了影响加固梁破坏特征及抗剪承载力的主要因素。

Based on 8 experimental beams, the failure characteristic and the shear carrying capacity of T-section restrained beams, which are strengthened with CFRP and GFRP wrapped by U-jacket are studied. And also,the main factors that influence the failure character- istic and shear carrying capacity of the reinforced beams are analyzed.
