FRP片材加固钢筋混凝土梁极限承载力试验

Ultimate capacity experiment on reinforced concrete beams strengthened with FRP laminate

制作了8根钢筋混凝土梁,考虑了混凝土等级、龄期、配筋、FRP加固情况等因素,对3组梁进行极限承载力试验,研究了纤维布加固钢筋混凝土梁的破坏模式、抗弯极限承载力、裂缝宽度、挠曲变形等内容。

Eight reinforced concrete beams were made, such factors ： the concrete grade, age, steel layout, FRP reinforcement, and so on were considered. The ultimate capacity of three groups beams were tested, the failure mode, the bending ultimate capacity, crack width, deflection, and other aspects were researched.
