不同胶层厚度对EB-FRP界面粘结性能的研究

Research on bonding properties of EB-FRP interface with different thickness of adhesive layer

外贴式(Externally bonded)FRP(简称EB-FRP)广泛应用于混凝土桥梁结构的修复与加固,其加固的效果取决于其界面的粘结性能。本文对不同胶层厚度下的界面粘结性能进行研究。分析可知,不同胶层厚度对界面的粘结承载力、破坏模式和损伤演化均有影响。

Externally bonded FRP(EB-FRP)is widely used in the repair and reinforcement of concrete bridge structures,and its reinforcement effect depends on the bonding performance of its interface.In this paper,the interfacial bonding properties of different adhesive layer thicknesses were studied.The analysis shows that different adhesive layer thicknesses have effects on the bonding capacity,failure mode and damage evolution of the interface.
