Abstract: A two-step method of non-linear finite element calculation based on one-span model is proposed to calculate the ultimate bearing capacity of the midship structure under the combined bending, shear and torsion loads. This method is then applied to calculate the ultimate bearing capacity of YOSHITERU T container ship and OSTAPENKO A box girder under the combined bending, shear and torsional loads. The proposed method has been validated and verified by comparing with the experimental results and the results from the other finite element models.

Key words: combined load, midship area, hull girder, ultimate bearing capacity

摘要： 提出了一种基于一跨模型的弯剪扭组合作用下船舯结构极限承载能力的非线性有限元计算的两步法。应用所提方法进行了YOSHITERU T的集装箱船和OSTAPENKO A的箱形梁在弯剪扭组合作用下极限承载能力的计算。通过与试验结果以及其他有限元模型结果比对,验证了文中所提方法的有效性和准确性。
