摘要
新材料和先进加工技术的进步使得钢材的屈服强度不断提高,为了取得更好的经济效益,冷弯钢材的厚度变得越来越薄。作为控制冷弯薄壁型钢承载能力的几种屈曲模式之一,畸变屈曲正逐步受到重视。本文总结了国内外对畸变屈曲研究的主要成果,并对几种常见荷载下的畸变屈曲计算进行了归纳。
The improvement in the strength of the cold-formed steel sections makes it possible to use thinner plates so as to achieve more economy in building construction. As one of several strength-governing modes, distortional buckling is receiving more attentions. Some main achievements on the distortional buckling analysis are summarized to ensure a better understanding of this phenomenon.
