Seismic performance under environment corrosion for curved beam bridges with high piers

Dynamic response under rare earthquakes of the small radius curved beam bridges with high piers under environment corrosion are studied and compared with the cases without corrosion in this paper by time history analysis method based on an actual project. The influence of pier-height and the environment corrosion on the seismic performance of bridges during the service life are studied, and the cumulative damage of piers is discussed.
