At present, the impact of the thickness and angle of corrugated steel webs on the response mechanism of key parts of the bridge under the action of earthquake is unclear. To explore the corrugated steel web plate thickness and twists and turns of corrugated steel web PC continuous rigid frame bridge seismic response mechanism of the key parts. In this paper, yanzhihe bridge of xifu expressway is used as the research object to establish the dynamic finite element model of multi-scale structure with ANSYS, and the seismic response is analyzed with the dynamic time-history analysis method. The results show that with the increase of the thickness of corrugated steel webs, the mises stress value of the corrugated steel webs decreases, and the relationship between them is inversely proportional. The wave Angle of corrugated steel web has little influence on the stress of steel web and seismic response of bridge pier especially the influence on seismic response of bridge pier can be ignored.
