摘要
冷弯薄壁型钢截面高效,在建筑钢结构领域得到广泛应用,随着冷弯型钢房屋结构布局、建筑层数等的变化,拼合截面构件的应用也越来越多。文中首先简要介绍了北美和我国关于冷弯薄壁型钢组合截面受压构件的设计方法,然后综述了国内外在冷弯薄壁型钢拼合截面受压构件的受力性能和设计方法方面的的研究成果,最后在分析的基础上提出冷弯薄壁型钢组合截面受压构件亟需解决的相关研究问题。
Cold-formed thin-walled steel structure has high section efficiency, which has been widely used in the field of construction steel structure. With the change of cold-formed steel structure layout and building floors, the application of built-up section members is increasing.This paper first briefly introduces the design methods of cold-formed thin-walled steel built-up section compression members in North America and China, then summarizes the research results of cold-formed thin-walled steel built-up section compression members in terms of mechanical behavior and design methods. Finally, based on the analysis, the related key research problems for the cold-formed thin-walled steel built-up section compression members are proposed.
