| Abstract: | A new method for determining the reliability of longitudinal strength of ship structure is presented,for studying the approximate probability of safety margin of ship's longitudinal strength in random short-term sea.For a specific example,the calculation process has been given in detail for dealing with the probability density function of the hull safety margin in short-term sea.It is shown that this method has a good application prospect in the field of hull longitudinal strength reliability analysis and e... |
