Abstract

Ice load is very important for the design of marine structures at low temperature areas. In order to reduce the ice load to the marine structure, it is common to pile with up-bending and down-bending cones. Therefore, the determination of the ice load acting on the up-bending and down-bending cone is crucial for the structure design. In this paper, unit force method was used to determine the ice load based on theory of structure mechanics and non-coordinate analysis of non-continuous body. Since the contact pressure between the cone and ice is unknown, a movable loading system with virtual stiff components is proposed and used to study the ice load on the up-bending and down-bending cone with multivariate nonlinear regression method. The result shows that with the up-bending and down-bending cone, the ice load acting on the pile is largely reduced.
