中文摘要：文章通过对国内外标准中关于油罐中间抗风圈设计计算的分析,尤其通过对抗风圈截面尺寸选取方面的理论分析与工程实例的比较,指出采用GB 50341-2005《立式圆筒形钢制焊接油罐设计规范》选取的中间抗风圈截面尺寸往往小于API 650-2010《Welded Tanks for Oil Storage》设计的截面尺寸,罐壁抗风稳定性存在一定的危险,建议在设计计算时可采用API 650-2010进行验证。
英文摘要：Through the analysis on intermediate stiffening ring design calculation methods from domestic and international standards,especially using theoretical analysis and engineering examples to make comparisons about how to cross-section size,this article illustrates that the intermediate stiffening ring cross-section size obtained from GB 50341 "Code for Design of Vertical Cylindrical Welded Steel Oil Tanks" is often less than that from API 650"Welded Tanks for Oil Storage",and there is a certain risk in the wind resistance stability of the tank shell.API 650 is recommended to validate the design and calculation of intermediate stiffening rings.
