In order to establish a total system to assess ultimate longitudinal strength of ship's hull girder under combined bending, torsion and shear, (1) efficient and accurate method of progressive collapse analysis of ship's hull girder under combined loads, (2) method of analysis of extreme wave loads on ships in rough seas, and (3) method of structural safety assessment of ship's hull girder based on structural reliability analysis were developed. Collapse tests of 1/13-scale container ship models under combined bending and torsion were carried out and their progressive collapse behavior and ultimate strength interaction relatioship were investigated.

为了建立一个总体系统，以评估船体船体梁的最终纵向强度在联合弯曲，扭转和剪切中，（1）在组合负载下对船舶船体船体的渐进式塌陷分析的有效，准确的方法，（2）基于船舶上的极端载荷的分析方法，基于船舶上的极端载荷方法，（3）结构性分析的构成型船体的安全性均可构成船体的安全性。在合并弯曲和扭转下进行了1/13级集装箱船模型的塌陷测试，并研究了其进行性崩溃行为和最终强度相互作用的关系。
