Inertial Coefficient Adopted in Pile-Pier Structure under Deep Water

Abstract:

In order to study the effect of hydrodynamic pressure acted on pile-pier structure in deep water, an investigation on the inertial coefficient is developed. Based on the Morison equation, the usual suggested value is analyzed, especially the noncircular slender cylinder is considered. Besides, the effect of scale of structure is studied, including accurate algorithm and approximation algorithm. Study results indicate that the Morison equation is also applied to noncircular slender cylinder, and the value of inertial coefficient is influenced by the scale of structure. Moreover, the calculated results of accurate algorithm and approximation algorithm are consistent within a certain range, so the choice of calculation method should be governed by the required precision.
