Abstract

Prior work by the authors has shown that moving ice loads incite a significantly different structural response in steel grillage structures than do stationary ice loads. The work was based on a validated explicit numerical model of a steel grillage. The main drawback was that the ice load model was largely unrealistic in terms of the distributed pressure and ice motions. The present work employs two realistic ice load models: a dynamic 4D pressure model, and a validated "crushable foam" ice model. Results using these realistic ice load models lend credence to previous findings and enable more realistic modeling of the whole ice-ship impact scenario.
