集装箱船在垂向弯矩和水平弯矩联合作用下的极限强度

用简化方法对集装箱船进行了垂向弯矩和水平弯矩联合作用下的极限强度分析。通过对船体在不同弯曲角度时极限强度的系列计算，得到极限弯矩的相关曲线。发现，由于集装箱船剖面的非对称性及屈曲引起的非线性使得结构构件拉压性能不同，相关曲线是非对称的。根据6艘集装箱船计算结果的统计分析，对适用于集装箱船的相关公式提出了建议。

Ultimate Strength of Container Ships under Combined Vertical and Horizontal Bending

The ultimate longitudinal strength of container ships was analyzed by a simplified method. The interaction curves for the ultimate strength of container ships under combined vertical and horizontal bending are obtained according to the results of a series of calculations for the hull subjected to bending conditions with different angles of curvature. It is found that the interaction curves are asymmetrical, because the hull cross-section of a container ship is not symmetrical about the horizontal axis and the behavior of the structural members under compression is different from that under tension due to the non-linearity caused by buckling. An interaction equation for container ships was proposed based on the statistics results of the calculation of 6 container ships.
