摘　　要：本论文针对集装箱船结构直接设计中所涉及的非线性波浪载荷疲劳损伤问题从理论方法、计算和应用等方面开展研究.采用谱分析方法,研究了非线性波浪弯矩及砰击弯矩对船体结构疲劳损伤的影响,并完成一个实例计算.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.
