The response of a multiplate ship hull plating under ice loading is studied both experimentally and theoretically. In the theoretical work, the frames are assumed to be rigid but the plates between the frames are flexible. In addition, the ice, which puts a patch-like loading on the plating, is assumed to be compliant. This ice-structure contact is modelled as a framed structure on a Winkler foundation. In the experimental work, the response of framed structures under ice loading was studied. Structures with different plate thickness were used. It is shown that the spanwise pressure distribution in a plate is determined by the rigidity ratio between ice and the plate: lower plate rigidity induces a deduction in ice pressure at the mid-span area. The plate stresses depend on the rigidity ratio and also on the aspect ratio of the plate. (C) 2002 Elsevier Science B.V. All rights reserved.
