In this study, a non-linear analysis method was proposed for serviceability evaluation of slab track at the end of a railway bridge. The conventional method of reviewing the serviceability of slab track at the end of a railway bridge is time-consuming due to the complicated evaluation process, and errors may occur in the calculation process. In addition, the conventional method of considering a rail fastening system as a linear stiffness model creates high uplift force, thereby requiring the installation of a special, expensive rail fastening system. Considering the nonlinear behavior of the rail fastening system, the proposed analysis method and the conventional analysis method for the actual railway bridge were performed together with the nonlinear analysis method. Using these methods, the uplift forces acting on the rail fastening system were compared and analyzed. The analytical method proposed in this study can result in a reduction of 15 to 35% in terms of the maximum uplift force. Also, considering the nonlinear behavior of the rail fastening system, the results of the nonlinear analysis method indicate a reduction of about 35% in the maximum uplift force.
