摘　　要：众所周知 ,界面粘结性能是钢筋混凝土结构修补成败的关键。采用非线性有限元方法 ,并发展了一种能反映界面粘结质量和力学特征的界面单元 ,对钢筋混凝土修补梁进行了系统的数值模拟 ,得到了十分有益的结果。经与试验结果比较 。It is well known that the performance of bonding interface is a key to the successful repair of a reinforced concrete structure.So the systematic numerical simulation of repaired reinforced concrete beam has been carried out with nonlinear finite element method.Especially a kind of bonding element is presented,which can reflect the bonding quality and mechanical behavior of interface.Finally some very interested results are got.The computation accuracy is satisfactory by comparing with testing results.
