［摘要］對于結(jié)構(gòu)和構(gòu)件的穩(wěn)定性驗算和分析，各國規(guī)范有共通之處也有諸多不同。我國各規(guī)范標(biāo)準(zhǔn)在制定時，雖部分參考了美國規(guī)范和歐洲規(guī)范，但有些內(nèi)容由于歷史原因以及結(jié)合我國自身特點，與發(fā)達(dá)國家規(guī)范有所不同。然而對于結(jié)構(gòu)設(shè)計而言，設(shè)計原理應(yīng)該是無關(guān)國別的。對各規(guī)范關(guān)于穩(wěn)定性分析中的二階分析方法進(jìn)行闡述，明確各規(guī)范中二階分析的發(fā)展現(xiàn)狀。同時，各規(guī)范明確規(guī)定或暗含了對于屈曲因子的限值要求。對此進(jìn)行剖析，以明確各規(guī)范對穩(wěn)定性設(shè)計的基本要求。

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
