Abstract : Ice forces are the principal concern in designing offshore structures such as drilling platforms, transloading points, or bridge peers in arctic regions. Although some results have been obtained by field measurements in recent years, there are still significant gaps in the knowledge of ice forces on structures. In order to fill some of these gaps, the Iowa Institute of Hydraulic Research has undertaken model studies on the investigation of ice forces on vertical piles. Model techniques for the study of ice-breaking phenomena have been developed, and the similarity between the model indications and prototype conditions has been demonstrated. Tests on the relationships between ice forces (ice strength) and pile diameter, ice thickness, and relative velocity (strain rate) between ice and structure have been completed.
