摘要
讨论了纯弯曲载荷下船体梁的极限纵强度．研究了船体梁断面的“硬角”、附连翼板宽度以及船体梁断面中性轴位置的变化对船体梁极限承载能力的影响．进行了纵向加筋箱形薄壁结构模型的纯弯曲试验．理论计算与试验结果比较表明，两者符合较好．
The ultimate longitudinal strength of the hull girder of a ship under pure bending load is discussed. The influence of 'hard corners' in the girder cross. section, the effective width of the attached plate and the variation of the neutral axis of the cross section on the ultimate bearing capacity of the girder is analyzed. Pure bending tests on the box-type thin-wall girder with longitudinal stiffeners have been carried out. It is shown that the experimental results agree reasonably well with the computed ones.
