轻钢结构设计中腹板屈曲后强度应用的探讨
Discussion on the application of web post-buckling strength in the design of light-weight steel structure
【摘要】 介绍了轻钢结构在我国的形成与发展,对目前国内外的研究成果及不足之处作了总结.阐述了我国现有的设计规范、标准对构件利用屈曲后强度设计方法的规定,指出了由于缺乏对轻钢结构设计方面,尤其对轻钢结构利用腹板屈曲后强度构件,对整体结构稳定及变形影响的规定而引发的不利之处.提出了应建立考虑材料非线性和几何非线性的理论分析与计算方法.
【Abstract】 With lightweight steel structure gradually becoming one of the main structure types in steel structure buildings, the problem of how to make use of postbuckling strength got more and more attention. In this paper, the formation and development of lightweight steel structure at home and abroad are detailed; domestic and overseas research results and deficiencies are summarized. Current code demands about the method of taking advantage of postbuckling strength are clarified and the disadvantages caused by lack of utilization of the effect of postbuckling strength on the whole structural stability and deformation are pointed out. Accordingly, several problems which are to be solved in the development of civil lightweight steel structure are put forward besides the questions mentioned.
