Hydrodynamic Pressure Effect Analysis of Double-Column Pier in Deep Water under Earthquake Actions

Abstract:

Taking the double-column pier as the research project, based on ABAQUS finite software, using the added water mass to consider the hydrodynamic pressure effect, considering the nonlinear of the soil and the concrete, building the hydrodynamic pressure effect model analysis of double-column bridge pier in deep water under earthquake actions, analyzing the hydrodynamic pressure effect on the relative displacement, acceleration, shear force, moment responses of pier and its hydrodynamic pressure coefficient under the earthquake. The results show that the earthquake hydrodynamic pressure changes the seismic responses characters of the pier, and increases the relative displacement and acceleration of pier top, and also increases the internal force of pier bottom. It is necessary to consider the hydrodynamic pressure effect in the bridge seismic design for comply with the actual situation better.
