［摘要］对于结构和构件的稳定性验算和分析，各国规范有共通之处也有诸多不同。我国各规范标准在制定时，虽部分参考了美国规范和欧洲规范，但有些内容由于历史原因以及结合我国自身特点，与发达国家规范有所不同。然而对于结构设计而言，设计原理应该是无关国别的。对各规范关于稳定性分析中的二阶分析方法进行阐述，明确各规范中二阶分析的发展现状。同时，各规范明确规定或暗含了对于屈曲因子的限值要求。对此进行剖析，以明确各规范对稳定性设计的基本要求。

Abstract:For stability analysis of structures and members, there are similarities and differences between specifications of different countries. Although the specifications of our country refer to the American and European specifications in part, they are different from those of the developed countries because of the historical reasons and the characteristics of our country. However, for structural design, the theory of design is independent of the nationality. The second-order analysis methods of stability analysis in various specifications were expounded, and the development of second-order analysis  was clarified. And the limit requirements for buckling factor are defined or implied in the specifications of each specification. This issue was analyzed in order to clarify the basic requirements for stability design of each specification.

Keywords:second-order analysis; steel structure; concrete structure; high-rise building; buckling factor
