Effect of pressure distribution on the capacity of ship structure frames

Recently there has been higher demand for ice-strengthened ships built in accordance with design standards such as Finnish Swedish Ice Class Rules (FSICR). The definition of the ice load in combination with the corresponding strength criterion is the most important part of the hull rules. The load level and its distribution defines the structural response, which is basis for evaluation of the design point. However, current rules do not consider the effect of different load distributions on the capacity of the frames. Here we show that length of the pressure patch and its distribution affect the capacity of the frames, and that current FSICR design approach is not the most conservative one. Therefore, we expect that this investigation becomes a basis for future investigations and possible rule modifications.
