FRP加固构件的粘结机理综述

The bonding mechanism and research of the component reinforced with FRP

用FRP材料修复或加固结构,荷载是通过粘结层在FRP与被加固构件之间传递的,所以粘结层的强度及耐久性对修复结构的整体性及安全性至关重要,研究FRP与被加固构件界面的应力分布和剥离机理对保证加固的有效性具有重要意义。近年来,许多试验及理论研究方法已经发展起来。

Reinforcing or repairing concretion with the FRP, load passes between the FRP and the reinforced concretion relying on the bending floor, so it is important towards the integer and security of the repaired concretion to the intension and wear of the bending floor, and researching the stress distributing is also on importance. Recently, most examination and researching theory have been developed.
