Abstract: This paper presents in detail the dynamic ice force process caused by bending failure of ice sheet acting on narrow cones based on full scale tests conducted on a multi-leg jacket platform which added with ice breaking cones. It is indicated that when ice sheet acting on a narrow cone the broken ice will totally clearing up by side of the cone. That mean the ice force will return to zero before the next action. The direct ice force measurement by ice load panel verified this phenomenon. The narrow cone referring to describe dynamic ice force is defined as broken ice floes could clearing up by side of the cone in the failure period of action.
