VERTICAL ICE LOADS ON OFFSHORE STRUCTURES DUE TO CHANGES IN WATER LEVELS

In very cold regions, vertical ice forces act on offshore structures, including bridge piers and intake towers, with ice sheets adfrozen to them as the water level changes. When the water level rises, vertical forces act upward to uproot the structure; when the water level falls, vertical forces act downward to buckle the structure. Therefore, the effects of vertical forces should be considered when designing structures upon which ice forces are exerted. In this paper, these ice forces are explained mathematically, and tables and figures are given for the practical computation of the ice forces with attention to destruction by adfreezing and bending. The addition, the interaction between the ice and the structure made of multiple piles was theoretically produced.
