3D Nonlinear Hydrodynamic Analysis of Vertical Cylinder during Earthquakes. I: Rigid Motion

Abstract

A finite-difference scheme was developed to solve nonlinear hydrodynamic pressures acting on a rigid vertical offshore cylinder during earthquakes. A complete three-dimensional (3D) analysis was conducted; not only were the three-dimensional equations of motion used, but the simultaneous action of three components of ground acceleration was also included in the analysis. The influence of the size factor [(defined as 2
