SUN WEI / ZHAO JIABAO / XIE ZIYANG

The invention provides a method for reinforcing a concrete structure by externally pasting FRP with anchoring, and relates to the technical field of building construction methods. The invention provides a method for reinforcing a concrete structure by externally pasting FRP with anchoring, the method is divided into two modes of bending-resistant reinforcing and shear-resistant reinforcing, the invention also provides a corresponding reinforcing design method and a construction and installation method thereof, and the method comprises the following steps: blending epoxy resin glue, preparing FRP ribs, trepanning, polishing, injecting glue, filling and curing the epoxy resin glue. The analysis model of the FRP strength ff and the correction modulus Ef is used for predicting the bending resistance of the FRP reinforced beam, and meanwhile, a corresponding shear reinforcement formula is provided corresponding to shear reinforcement. According to the scheme, the method can be used for repairing the existing RC component, and the bending resistance and the shearing resistance of the RC component are improved.

本发明提供了一种带锚固的体外粘贴FRP加固混凝土结构的方法，涉及建筑施工方法技术领域。本发明提供的一种带锚固的体外粘贴FRP加固混凝土结构的方法，分为抗弯加固和抗剪加固两种方式，同时提出了相应的加固设计方法，及其施工与安装方法，包括如下步骤：调配环氧树脂胶、制备FRP筋、开孔、打磨、注胶、装填、环氧树脂胶固化。运用FRP强度ff和修正模量Ef的分析模型用于预测FRP加固梁的抗弯性能，同时对应剪力加固提出相对应的抗剪加固公式。通过本方案可用于修复现有的RC构件，提高RC构件抗弯和抗剪性能。
