To study the progressive collapse resistance of the elevated station, LS-DYNA software was used to establish the pure frame numerical simulation model for the elevated station in Xi’an Station, and 1–3 columns in the corner area and in the middle area were removed for numerical simulation analysis. The results show that the elevated station has good robustness. Under the conditions of single column removal and double columns removal in the middle area, the beam mechanism is the main resistance mechanism, and the catenary mechanism is developed under the three columns removal condition. Finally, the influence of the floor on the collapse resistance of the high-speed railway station was analyzed, and the results show that the deformation of the structure can be effectively reduced, and the collapse resistance of the structure can be improved by the tensile membrane mechanism of the floor under the large deformation of the two columns and three columns removal.
