摘要

采用指数函数分析模型拟合纤维增强复合材料（Fiber Reinforced Plastic

FRP）与混凝土粘结界面单剪试验的荷载滑移曲线

在现有分析模型基础上

提出一个基于粘结界面单元采用损伤演化方法输入粘结界面本构关系的分析模型

并基于该模型提出一种FRP-混凝土界面粘结性能的有限元分析方法。结果表明:本模型能较精确地反映剥离破坏过程中FRP的荷载滑移关系和应变分布。通过有限元分析得出的荷载滑移曲线与分析模型完全吻合

FRP应变分布与实验结果也吻合较好。验证了分析模型的正确性和精确度以及该分析模型的有限元模型的正确性。

Abstract

This paper uses the exponential function analytical model to fit the load slip curve of the interface of fiber reinforced plastic（FRP）-concrete in the single shear test.Based on the existing analytical models

this paper proposes an analytical model

which adopts a damage evolution method to input constitutive relation of the bonding interface

and based on this analytical model

this paper proposes a finite element method（FEM）of the FRP-concrete interface.The results show that this model can accurately reflect the load-slip relationship and strain distribution in the process of FRP debonding.The FEM results coincide with the analytical model in the load slip curve and reach full agreement with experimental results in FRP strain distribution.These have great validity and accuracy of the proposed analytical model

and also have the validity of the FEM based on this analytical model.
