Abstract

Based on static experimental research, the major factors that influence strengthening effect and the destroyed mode of the steel beam bolt splicing joint strengthened by CFRP are observed. The numerical modeling has been done by the bolt splicing joint finite element analysis model considering the contact friction and the pretightening force. The contribution to the yield load and rigidity by the bolt joint strengthened by CFRP has been analyzed. The finite element analysis result and the test result show that the strengthening method is effective.
