Critical load between sea ice and sea structure

The main objective of this paper is to propose the buckling equations of the sea sheets under concentrated forces. Two different cases of the acting forces are considered in this paper and the buckling equations of them are deprived, respectively. Then, the dimensionless forms of these equations are given. Furthermore, by adopting a numerical method, two cases of different thickness of the ice sheet and different distances between sea structures are explored. On the basis of the buckling equations, the expressions of the critical load between sea ice and sea structures are obtained. Finally, the relationship between the critical load factor and the dimensionless radius are presented.
