[提要] 對(duì)交錯(cuò)鋼桁架結(jié)構(gòu)的側(cè)移分析，采用連續(xù)化的數(shù)學(xué)模型和側(cè)向抗剪剛度法。此方法概念清楚，計(jì)算簡(jiǎn)便，并舉有算例以說(shuō)明其應(yīng)用。
[關(guān)鍵詞] 交錯(cuò)鋼桁架結(jié)構(gòu) 側(cè)移分析 側(cè)向 抗剪剛度The analysis of sidesways of staggered steel truss structure is discussed. The mathematical model of an equivalent continum is proposed and solved by the lateral shear rigidity method. The suggested method is clear in conception and convenient in calculation. Finally, a numerical example is shown for reference is designing.
Keywords: staggered steel truss structure; analysis of sidesways; lateral shear rigidity
