Abstract: The ice-structure interaction can be investigated by laboratory experiments or computer-based simulation. In both cases the mathematical model describing the mechanical behaviour and strength properties of ice is needed either to apply results of laboratory small-scale tests to a real structure or to construct a numerical model of the interaction process. Strength criterion seems to be one of the most important elements of this model. The computer model of the level ice action onto wide vertical-faced offshore structure was developed at the Saint-Petersburg State Technical University in 1985-1989 and realised as FORTRAN computer code "SHELF-M". It incorporates the modified Coulomb-Mohr strength condition as a strength criterion for ice. The principal aim of this paper is the comparison of the results of computer-based simulation under various strength criteria. Their influence onto maximum ice load and interaction process is investigated.
