摘要
本文根据国内外研究现状 ,综述了新近轻型钢结构中梁及檩条稳定性方面研究的若干内容。首先简要介绍了目前轻钢结构的发展特点 ,然后着重就薄壁型钢梁及檩条的截面特性、屈曲行为及其研究方法以及稳定性方面研究的几个热点问题作了概述 。
The paper summarizes the recent advances in stability of cold-formed steel beams and purlins. It contains three components. Firstly, it reviews the developments in cold-formed steel structures over the last recent years. Secondly, it summarizes the development of cold-formed sections and latest trend about stability of cold-formed beams and purlins. Finally, some possible improvements in stability of cold-formed beams and purlins are anticipated.
