12th International Symposium on Ice, 23-26 August 1994, Trondheim, Norway
Ice rubble buildup has a direct effect on the loads imparted to conical structures and contributes to ice breaking loads as well. Based on model scale observations, a simple model has been development for the ice clearing process. An upper limit for ice accumulation against the front slope of a cone is provided using a finite element solution which included provision for crushing at the contact between the ice sheet and the structure. These results have helped to achieve consistent rubble surcharge data for probabilistic ice load models.
