摘要: 纤维增强复合材料(FRP)因其轻质、高强、耐久而被广泛用于房屋建筑结构的修复和加固中。FRP能改善加固系统的力学性能，提高砖砌体结构的整体性。而提高整个结构的整体性的关键就在于FRP与砖砌体之间的粘结性能，通过粘结剂的粘合作用，将作用在FRP上的剪力传递给砖砌体基层，从而提高结构的抗弯、抗剪强度。因FRP加固结构的粘结强度受到界面粘结性能的影响，本文收集了近年来国内外学者对FRP加固砖砌体的一系列试验研究和理论分析，总结了砂浆接缝强度、劣化环境条件对界面粘结性能的影响，以及不同的RP加固方式对整个加固系统承载能力的改善情况的相关研究，整理出目前主要的FRP-砌体界面粘结承载力的计算经验公式。针对目前FRP加固砌体结构领域仍值得研究的相关问题进行分析，为今后拟开展的相关研究提供一定的参考价值。
Abstract: Fiber reinforced Polymer (FRP) is widely used in the restoring and reinforcement of building structures due to their light weight, high strength and durability. FRP can improve the mechanical properties of the reinforcement system and improve the integrity of the brickwork structure. The key to improve the integrity of the whole structure lies in the bonding properties between FRP and brick masonry. The shearing force acting on the FRP is transmitted to the brick masonry substrate by the cohesive effect of the binder, thereby improving the flexural and shear strength of the structures. Because the bond strength of the reinforcement system is affected by the interfacial bonding performance, this paper collects a series of experimental and theoretical analyses for external strengthening of masonry structures by domestic and foreign scholars in the past five years, and summarizes the influence of the mortar joint strength and degraded environmental conditions for the interface bonding performance and the improvement of the bearing capacity of the whole reinforcement system by different external bonding FRP methods were compiled, and some calculation formulas of the bonding capacity of FRP-masonry interface were concluded. Aiming at the current research on masonry structures reinforced with FRP, some problems are raised, which provide some reference value for the related research to be carried out later.
