[摘要] 區(qū)別于傳統(tǒng)的長度系數(shù)法的設(shè)計方法，二階分析逐漸在鋼結(jié)構(gòu)設(shè)計中得到推廣并為各國規(guī)范所推薦。美國鋼結(jié)構(gòu)規(guī)范AISC360附錄7中給出了考慮二階效應(yīng)（Second Order Effect）的設(shè)計方法——直接分析法（Direct Analysis Method）。STAADPRO作為國際工程中廣泛應(yīng)用的結(jié)構(gòu)分析軟件，內(nèi)置了美國鋼結(jié)構(gòu)設(shè)計規(guī)范的全部功能。本文就二階分析法的概念及在STAADPRO軟件中的具體應(yīng)用給出了推薦意見和實踐方法。[關(guān)鍵詞] 美國規(guī)范AISC360; 二階分析; STAADPRO中圖分類號：TU318.4 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2013)S2-0509-03作者簡介:王文彬，男，工程師，Email：wangwenbin@nwepdi.com。Second order analysis of American Steel CodeWang Wenbin(Northwest Electric Power Design Institute, Xi’an 710075, China)Abstract: Different with the traditional steel design method of effective length, second order analysis is now adopted and recommended by many steel design codes. In appendix 7 of American steel design code of AISC360, the detail provisions are provided for second order analysis, which is named of Direct Analysis Method. STAADPRO is widely used structural analysis software in international engineering, which have the all steel design function set in software. This article is trying to introduce some recommended suggestions and practices in STAADPRO for the second order analysis.Keywords: American Code AISC360; second order analysis; STAADPRO
