针对不同界面连接形式的FRP板与混凝土进行单剪试验,重点研究破坏形式、极限承载力及破坏机理等内容,研究表明:布置单向剪力连接件时,增加连接件数量、减小连接件间距可以提高界面抗剪承载力,也可改善构件弹性阶段整体刚度;提出的双向格栅剪力连接件可明显提高界面整体抗剪承载力,并可增强弹性阶段构件整体刚度.
For the different interface connection form of FRP board and concrete for single shear test,focusing on the destruction of the form,the ultimate bearing capacity and damage mechanism and so on.The results show that increasing the number of connectors and reducing the spacing between the joints can improve the interface shear capacity and improve the overall elactic stiffness of the members when arranging the unidirectional shear connections.The proposed two-way gration shear connector can significantly improve the overall shear strength of the interface and enhance the overall stiffness of the elastic phase member.
