Abstract: To improve the seismic performance of high-speed railway simply-supported girder bridge (HRSGB) near-fault, combined with the concept of rocking pier, buckling restrained brace (BRB) and shear-friction dampers were selected in this paper as the external energy dissipations (ED), and self-restoring forces were provided by prestressed tendons to form a HRSGB system with rocking self-centering energy dissipation column (RSC-EDC) inside the pier. Taking the capacity curve of the system as the performance indicator, a seismic design method which was based on the equivalent energy-based design procedure (EEDP) was developed. Initially, the numerical model of a HRSGB with RSC-EDC inside piers was established by OpenSees software. Combining the Code for seismic design of railway engineering and EEDP, a three-stage design method was proposed for the HRSGB system with RSC-EDC inside the pier. Then the energy modification factor was calculated by nonlinear time history analyses. Finally, a design example was used to prove the correctness and practicability of the proposed design method. The results show that the design procedure can well predict the performance state of the HRSGB system with RSC-EDC inside piers under different level earthquakes, achieving the design goal of maintaining elasticity of all components of the system under frequent earthquakes, yielding energy dissipation of the BRB and the shear system of shear-friction dampers under design earthquakes, sliding energy dissipation of the friction system of shear-friction dampers under rare earthquakes.
