Summary. It is widely admitted that the reliability criteria give the possibility of a more rational approach to structural problems.
The exact and approximate probabilistic methods usually applied to structural problems have been firstly reviewed. Thereafter, a general definition of the safety index has been given, which can be applied to generically distributed variables without any space transformation {obviously except the usual transformation in the standard space).
As regards the longitudinal strength of ship, a general expression for the limit state has been considered and discussed in detail.
Finally, a method has been formulated to assess the actual value of the safety index according to the proposed formulation. A numerical application has been carried out and results have been discussed.
