Abstract
Under earthquakes, bridges in icy water are subjected to both hydrodynamic pressure and dynamic ice force, and yet effective calculation methods for seismic analysis are not available. In this article, based on the test and numerical study on hydrodynamic pressure and dynamic ice force, a simplified calculation method for seismic response analysis of bridge piers in icy water was established to analyse the influence of free ice and consolidated ice on seismic responses of the pier. Comparison was carried out between the FEM analysis and shake table test, and the results showed that the simplified calculated method is efficient and accurate.
