Uncertainty and joint probability of sea ice loads

Ice load is one of the most important factors for design of marine structures in mld sea area.The design criteria of ice Loads for marine structures consist of two parts., level ire thickness and crushing strength.Due to the strong randomness of the affecting factors on ice thickness and crushing strength, such as ice temperature, air temper-store, water temperature, salinity, wind field, numerical simulation method cen not produce satisfactory results.This paper proposes a method of uncertainty analysis and joint probabilistic prediction of level ice thickness and crushing strength instead of traditional ice load criteria for marine structures.
