Abstract
Based on the perspective of earthquake resistance, the dynamic characteristics from construction to completion is analyzed and compared with each other for three typical long span continuous girder bridges with different types of piers constructed by balanced cantilever method, the vase-type solid pier, the thin-wall type hollow pier and the double-column type solid pier. The variation law of the dynamic characteristics along with the construction stages is obtained and the comparison law of the dynamic characteristics is obtained among the three bridges. It shows in a great degree that the seismic performance analysis and the seismic design nowadays, which are only based on the 1st period and mode in the completion state of the bridge, are not reasonable very much. The seismic performance analysis and the seismic design should consider all construction stages for the bridge constructed by the balanced cantilever method.
