Abstract Research purposes: To ensure the safety, reliability and economic rationality of single-column elevated station structure seismic design, the performance-based seismic design method is systematically studied. Firstly, the Midas-civil model of the structure is established to study its dynamic characteristics, and the seismic checking calculation of the main stressed components under low-level, medium and high-level earthquakes is carried out. Then, the ABAQUS finite element model of key beam-column joint is established, and the stress state of the joint region under normal service stage and high-level earthquake is studied.
Research conclusions: (1) According to the structural characteristics, the seismic performance targets under the building structure code and railway code are set respectively. (2) The results of response spectrum and time-procedure analysis under low-level earthquake show that the maximum interlayer displacement angle meets the performance target requirements; under the medium earthquake condition, the checking results of pier column and cap beam meet the performance target requirements. (3) The results of elastic-plastic time-procedure analysis under high-level earthquake show that the section of pier column members is cracked, but the internal reinforcement does not yield and the hysteresis curve is linear. (4) The finite element analysis of beam-column joint shows that the concrete on the upper surface of the joint is cracked slightly, and the internal reinforcement does not yield under the high-level earthquake condition, which meets the requirements of non-yield under high-level earthquake. (5) The research results can provide reference for the seismic design of elevated station structure.

Key words： single-column elevated station performance-based seismic design beam-column joint finite element
