摘要
为保证大型集装箱船营运中的安全性和航行时的结构可靠性,国际船级社协会专门针对集装箱船的规范要求进行修改,提高了载荷设计值,并要求评估典型货舱结构的极限承载能力。针对万箱集装箱船典型货舱结构,文章基于逐步破坏法和有限元法,计算垂向和水平方向的极限弯矩。结果表明,在初步设计阶段,逐步破坏法有着快速高效的优势,但是考虑到载荷变化的多样性和船体结构的复杂性,仍需要应用非线性有限元法进行建模计算,给出最终评估结果。
In order to ensure the safety in operation and the reliability of the structure,IACS has revised the unified requirement of the container ships specifically to increase the design loads,and required assessment of the,ultimate limit state bearing capacity of a typical cargo hold structure.Aiming at the typical cargo hold structure of 10000 container ships,the ultimate bending moment in vertical and horizontal direction are calculated based on the progressive collapse method and the finite element method.The results show that the progressive collapse method has the advantage of fast and high efficiency in the preliminary design stage. However,considering the diversity of load changes and the complexity of the hull structure,the nonlinear finite element method is also required for the modeling calculation and for giving the final assessment.
