Earthquake-Induced Added Hydrodynamic Pressure on Circular Hollow Piers in Deep Water

  • Based on the radiation wave theory,a liquid control equation for hollow circular piers was deduced under the condition of free surface wave,the movement boundary condition of bottom water particles,and the continuity condition of structure and water velocities.By applying the variable separation method,a method of calculating the velocity of water in the inner area of a hollow circular pier was gained.Furthermore,an analytical method for added hydrodynamic pressure of water in the inner area of a hollow circular pier was proposed.A calculation of the added hydrodynamic pressure for Rion-Antirion bridge in Greece shows that the added hydrodynamic pressure will result in the increases of bent moment and shear force,and the effect of water in the inner area of a hollow circular pier can not be neglected.
