A bridge across the Yellow River is one of the most extensively applied PC continuous beam bridges. In the article the seismic response of the bridge is analyzed, the key points of the seismic design are elaborated, the seismic behavior of the bridge is evaluated according to the design of the bridge and the results of finite element analysis, in order to ensure the safety of the bridge, which has a certain refer-ence value to the seismic analysis of the ultra long continuous girder bridge. The results show that the combination of the reasonable seismic design thought and the effective earthquake resistance measures can obtain ideal effect.
