According to the location of the bridge,the selection of E1 and E2 earthquakes and the corresponding seismic time curve,and then establish the whole bridge finite element model,and use the reaction spectrum method to study the seismic response of the arch bridge structure in E1 and E2 earthquakes.The results show that the arch ribs are in a safe state in both levels,and the result of the linear time history analysis is about 80%larger than that of reaction spectroscopy.
