Viscoelastic approach to the ice load evaluation

Juri Kajaste-Rudnitski, William Sackinger

Research output: Book/ReportReport


Ice field measurements around the concrete cylindrical lighthouse in the Gulf of Bothnia were carried out in the middle of March 1984 employing sensors of different design and purposes. Relatively low ice activity at the period enabled the use of linear ice/structure interaction models for evaluation of the ice loads transferred to the lighthouse as well as linear constitutive material relations when dealing with ice rheology. In the present analysis the information coming from the strain sensors embedded into ice is interpreted into forces on the basis of hereditary viscoelasticity with references to the same data from other sources. The advantages and flaws of the method are discussed.
