Based on the simplified dynamic response calculation model of the bridge pier under the coupling effects of seismic loads and dynamic ice force, the effects of consolidated ice on the seismic performance of the bridge pier are studied. The results show that consolidated ice can even enlarge the maximum curvature of the bridge pier several times and generally enlarge the ratio of collapse more than 15%, especially under the far-field seismic waves. The Collapse Margin Ratio (CMR) of bridge pier surrounded by consolidated ice is significantly smaller than the acceptable CMR, which means the bridge pier surrounded by consolidated ice cannot meet the requirements of collapse-resistant capacity. It is necessary to consider the coupling effects of seismic loads and dynamic ice forces when design a bridge in icy water.
