摘　　要：在分析UR S11A和S34生效后的集装箱船整船屈服、屈曲要求的基础上,以1艘支线集装箱船为对象,计算得到目标船整船结构各个计算工况下的应力分布,完成整船屈服、屈曲强度评估和疲劳筛选及评估,分析发现支线集装箱船艏、艉非货舱区域结构和货舱区域的横向结构,以及整船重点区域的疲劳问题不容忽视。在设计时,对上述区域结构应重点关注,必要时建议选择装载手册中最危险的工况开展整船屈服、屈曲和疲劳评估并作适当加强。The requirements of yield and buckling of the container ship with the UR s11A and S34 codes in force was investigated.Taking a feeder container ship as the research object,the stress distribution of the whole ship structure was calculated,and the yielding,buckling strength assessment and fatigue evaluation of key area nodes were completed.It was found that the fore end and aft end structure,the transverse structure of cargo area and the problem of key area of the whole container ship cannot be ignored;during the design,the above regional structure should be paid more attention to.If necessary,it is suggested to select the most dangerous loading conditions to carry out yielding,buckling and fatigue assessment of the whole ship and make appropriate strengthening.
