Effects of Cross-Sectional Shape on Vertical Ice Load Acting on Pile Structure

摘要

In cold regions, vertical ice loads act on pile structures with ice sheet adfrozen to them, as the water level changes due to tides. Therefore, vertical ice loads must be considered fully in the design of offshore structures. In addition to developing theoretical equations to calculate ice load, their verification based on a limited number of full-scale experiment was made in this research. In the experiment, we compared ice loads acting on piles with three different cross-sectional shapes (circular, elliptical and square) and found a circular cross-section to be the most effective, i.e., to receive the lowest ice load.
