摘要 对比了EN 1993-1-4∶2006《欧洲不锈钢结构设计规范》、SEI/ASCE 8—02《美国冷成型不锈钢设计规范》和日本《不锈钢建筑结构设计基准》(2002)中压弯构件平面内稳定的设计方法,并结合不锈钢轴心受压构件稳定承载能力的研究成果,基于GB 50018—2002《冷弯薄壁型钢结构技术规范》中相关规定,考虑不锈钢材料力学性能的离散型,提出不锈钢压弯构件平面内弯曲屈曲的设计公式;将设计方法计算结果与国外已有的试验数据进行对比。结果表明,所建议公式的计算结果与国外基本规范具有相近的精度,计算结果偏于安全;最后,对不锈钢压弯构件的设计表达式的改进方向进行展望。该设计表达式可为编制我国不锈钢结构设计规程中压弯构件设计条文时参考。 Design methods about stainless beam-columns that are buckling about the axis of the bending in three typical stainless design codes, Code of America ( SEI/ASCE 8 - 02) , Eurocode ( EN 1993 - 1 - 4: 2006) and Code of Japan ( 2002 ) are compared. A design method of beam-columns based on the Technical Code of Cold-Formed Thin- Wall Steel Structures (GB 50018-2002) and the previous research achievements in columns is proposed. Comparisons among three specifications and experiment results indicated that the calculated results by the proposed method have similar accuracy with those of these specifications and are conservative on average. Some improvements to this method in the future are given in the end. Conclusion can be used as a reference for the first version for stainless steel design code of China.
