ABSTRACT

In the present paper two important correlations between short-term wave and whipping bending moments are presented. Furthermore, the shortterm probability distribution of combined bending moment is suggested. The study is based on the most probable short-term load combination factors which are derived from the reconstruction of time signal from the frequency domain. As an input for this method the vertical wave bending moment is calculated based on seakeeping analysis, while the whipping bending moment is obtained based on transient dynamic response of Timoshenko beam. This approach is justified by the fact that hydroelastic coupling between whipping response and impact load is not significant as for the springing analysis.
