| 摘 要： | 针对国际船级社协会双壳油船共同结构规范中加筋板屈吐和极限强度的计算要求，介绍了其技术背景和国内外相关研究现状，并通过分析各种因素对加筋板屈曲和极限强度的影响，研究国外相关技术文献，提出了一套完整的加强筋屈曲和极限强度有限元计算方法。与共同结构规范中要求的对标数据进行对比，验证了该方法的正确性。

| Abstract: | The technical background and the current research status at home and abroad of the assessment requirements of buckling and ultimate strength of stiffened panels in IACS Common Structural Rules for Oil Tankers was introduced. An integrated FEA method was put forward based on the analysis of the influence of varied factors and the study on the relevant technical litera- tures. A comparison between the FEA results and the benchmark data in CSR was provided to verify the method. |
