Reliability analysis of static ice force on the action between ice and structure

There are almost three months of ice period in the Bohai Sea, and the ice force is more powerful than the force of wave on the structure in winter.So, it is necessary to analysing the reliability of static ice force on the process action between ice and structure.First, a numerical simulation of the sea ice thickness on the lines of environment parameters is made based on practical measurements every year, and is compared to other literature.Second, the statistic distribution of sea ice strength is given, taking the strain velocity as main effect during of numeration.Finaly, the reliability of static ice force for different reccurrence periods is calculated by taking Schwarz formula as formula of calculating static ice force and results are simulated by Monte Carlo important sampling method.
