THE EFFECT OF NON-LINEARITIES ON THE PROBABILITY OF FAILURE OF SHIP STRUCTURES

In the present paper some non-linear reliability problems relating to failure of the main hull girder of a ship are studied and discussed. In the first part of the paper the long-term probability of failure is considered under the assumption that the load due to waves is exponentially distributed and that the distribution of the strength of the hull girder is given as a non-linear function of a set of stochastic variables. In the second part of the paper the short-term probability of failure of the hull is analysed, assuming the strength to be given as a deterministic quantity and the load due to the stationary stochastic seaway to be given by a quadratic function relationship. Based on these studies some conclusions are made on the necessity of taking into account non-linear effects in the calculation of the probability of failure of ships in a stochastic seaway.
