摘要
基于ABS和DNv规范关于剩余强度规范要求,对船舶碰撞与搁浅的破损部位和范围的假定,考虑了发生碰撞与搁浅破损后,其船体梁剩余有效剖面的非对称性和可能发生不同程度倾斜的情况,采用结构共同规范(CSR)中的逐步破坏分析方法和船体梁非对称剖面计算模型,分别计算了散货船和油船破损船体在两种破损模式和不同倾斜情况下的剩余极限强度,并对不同破损范围的影响进行了分析和比较。研究结果为协调结构共同规范(HCSR)的制定提供了有价值的参考。
The study of this paper is to analysis the certain bulker carrier and VLCC tanker on the residual ultimate strength using the progressive collapse methodology defined in IACS common structural rules and with the considering the asymmetrical cross-section model of hull girder and heeling changes due to two damage assumptions of collision and grounding which damage extents based on ABS and DNV rules, also the influence of assumed damage extents is evaluated. The outcome of this paper can be the valuable reference for the development of Harmonized Common Structural Rule.
