Hook bolts are used to fix railroad sleeper and bridge girders in a railroad bridge. The type of hook bolt is roughly divided into a J-shaped one and a L-shaped one (hereinafter referred to as a L-shaped hook bolt). Research on fastening characteristics of J-shaped hook bolts has been researched by the authors, but L-shaped hook bolts are scarcely investigated, whose design is mainly dependent on experience. Therefore, in this study, based on the beam theory model, experiments and Finite Element Method (FEM), we investigated the influence of the arm length of the L-shaped hook bolt on the axial force and the torque coefficient, and clarify the fastening characteristics.
