摘　　要：采用反演分析法确定单剪FRP板-混凝土试件界面的黏结应力-滑移关系.该法无需测量FRP板拉拔过程整个界面的黏结应力-滑移关系,而是根据拔出力和裂纹嘴处测量的单剪FRP板-混凝土试件的相对剪切滑移确定黏结应力-滑移关系.最后对FRP板-混凝土单剪试件进行了有限元分析,分析结果与数值分析结果吻合很好,说明该方法可以应用于双材料结构的工程设计中.An inverse analysis was carried out to determine the bond-slip relationship of FRP sheet-concrete interface in simple shear tests.By use of this method,the measurements of bond stress-slip relationship on the whole interface during pulling process of FRP were not required,and only the pulling force and the relative shear displacement of FRP sheet-concrete specimens at the crack mouth were needed to yield the bond stress-slip relationship.The FEM analysis of the FRP sheet-concrete specimens was performed.The analytic results exhibited satisfactory agreement with the numerical ones.A conclusion is drawn that the proposed method can be applied to the design of bi-material structural members.
