naval ship structure

This paper study on naval ship structure direct design methods by reference the commercial direct calculation methods and naval ship structure design rules.

本文参考民船结构直接计算的方法，结合舰艇结构设计规范，研究舰船结构直接计算方法和解决方案。

For a naval ship with a long strength superstructure and a lot of hatch, it is difficult to evaluate the hull girder's strength by general beam theory because of the complexity of the hull structure.

当舰船设有长度较长但开口较多的上层建筑时，其船体结构的复杂性使船体总强度很难用常规的梁理论方法确定。

Structure direct calculation methods have succeed in commercial ship design, but in the naval ship design, it still underway, there have no guidelines for direct analysis in our naval ship rules.

结构直接计算法在民用船舶设计中已经取得许多成功经验，但在军用舰船中的应用还处于起步阶段，我国军船规范中还没有进行舰艇结构直接计算的指南。
