摘要
Abstract
In this paper,a method of obtaining the interface shear cohesion model by the pull shear test combined with the finite element method is presented,and the feasibility of the method is verified from the energy release rate.The load-loading displacement diagram of the interface was obtained by the uniaxial shear test of the resin/concrete bonded specimen.Based on the bilinear cohesive shear model,the characteristic of the interracial cohesion model was obtained by analyzing the shear process.The maximum stress and the characteristic displacement of the interface cohesion model are obtained by the finite element simulation.Finally,the energy release rate and the calculated energy release of the shear test are compared.The rate,the relative error between the two is within 10％,suggesting that the method of calculating cohesion is feasible.关键词
