When performance-based structure design is adopted, the structure has a clear structural performance objective under the specified setting criteria, and the performance target is specifically reflected in the damage degree of the structure. The components of the “bridge-building” structure are mainly concentrated on the pier column of the station hall. Therefore, the degree of damage of the pier column of the station hall layer reflects the degree of damage of the structure to a certain extent. This paper describes the earthquake-resistant ductility of the combined bridge structure. The performance indexes were quantitatively analyzed. Then, through the elasto-plastic analysis of the structure, the influence of various factors on the seismic ductility of the structure was obtained. The ductility of the piers under the earthquake was discussed, which provided a reference for structural design.
