| 摘 要： | 根据IACS共同规范（CSR），针对散货船结构，采用逐步递增破坏分析法计算船体结构的极限承载能力，同时编制了计算程序。对典型箱型梁模型和一艘散货船极限强度的计算结果表明，我们所开发的计算程序是正确可靠的。此外，对影响散货船极限强度的参数进行了敏感度探讨，计算结果表明屈服应力和板厚对船体极限强度的影响很大，应着重考虑。

| Abstract: | We analyzed the ultimate strength of a bulk carrier using the incremental-iterative approach based on the Common Structural Rules for Bulk Carrier by IACS. Hence a program in FORTRAN language was developed to calculate the ultimate strength of the box structure and the bulk carrier. The sensitivity of several parameters to the ultimate hull bending moment of the bulk carrier was discussed. The ultimate strength of hull is dependent largely on the yield stress and the plate thickness. The calculation results obtained by the program were also compared with the results of related literature reported in the International Ship and Offshore Structures Congress. The comparison indicated that the program developed is reliable and has a good accuracy. |
