| 摘 要： | 对于船舶结构设计中经常碰到的上层建筑参与船体总纵弯曲程度这个问题,即上层建筑有效度问题进行研究。有效度的正确计算判断不仅有助于上层建筑结构的合理布局,而且能避免各种裂纹的出现,提高船舶的使用寿命。现代工程设计常采用不同的近似计算方法来评估有效度,而这些近似计算方法的精确度及适用范围则需要通过试验来加以验证,以便给工程设计提供一定的指导。

| Abstract: | How to contribute to the hull girder strength for the superstructure,namely,the superstructure effectiveness is often considered on the design of ship structure.Correct calculation of superstructure effectiveness can not only help the structure design of superstructure,but also avoid the appearance of cracks and extend the service life of ships.On modern project design,various approximate methods are used to estimate the superstructure effectiveness.The precision and applicability of these methods should be... |
