| Abstract: | In this paper, some aspects such as the nonlinear wave loads, torsion strength, fatigue damage, in the container ships＇ direct calculation are systematically studied. With the spectrum analysis method, the contribution of slamming and nonlinear wave induced bending moments to structure fatigue damage is studied. The cumulative damage approaches are compared with each other in short-term and long-term scopes. Fatigue of a container ship is calculated. Some meaningful conclusions are achieved. |
