摘要
为了研究增强筋插入式加固钢筋混凝土梁的变形性能,通过试验和理论计算分析结果表明,玄武岩纤维筋绑扎加固、玄武岩纤维筋插入式加固和普通钢筋绑扎加固3种加固方法都能很明显地改善梁的变形性能,所有梁跨中挠度的计算值均小于混凝土结构设计规范所规定的在标准荷载作用下挠度限值,按混凝土结构设计规范(GB 50010—2010)给出的刚度公式所计算出的跨中挠度具有足够的安全储备。
In order to study the behavior of strengthened concrete beam deformation with reinforced bars inserted, test research and analysis result of theory calculation show that deformation behavior of beams can be improved obviously by three kinds of strengthening methods. The calculation value of all middle span deflection is totally less than the limited deflection under standard load ruled by concrete structure design code. The middle span deflection calculated with the stiffness formula given in the concrete structure design code （GB 50010—2010） has enough emergency capacity.
