[提要] 依據(jù)《門(mén)式剛架輕型房屋鋼結(jié)構(gòu)技術(shù)規(guī)程》,建立了輕型房屋鋼結(jié)構(gòu)(簡(jiǎn)稱門(mén)式剛架)離散變量?jī)?yōu)化的數(shù)學(xué)模型,應(yīng)用離散復(fù)合形優(yōu)化方法,在3D3S( V3.0)軟件的基礎(chǔ)上編制了門(mén)式剛架的結(jié)構(gòu)優(yōu)化程序。算例表明,該方法實(shí)用可靠,快捷方便,經(jīng)濟(jì)效益明顯。
[關(guān)鍵詞] 門(mén)式剛架 結(jié)構(gòu)優(yōu)化 離散變量?jī)?yōu)化Based on Technical Spec,i[ication for Steel Structure of Steel One-story Light-weight Building with Gabled Franzes, the optimization model of steel one-story light-weight building with gabled frames via discrete variables is built, and the complex method with discrete variables is improved. Optimization programming is implemented in the space steel system CAD software-3D3S. Numerical examples illustrate the method is reliable, convenient and efficient.
Keywords: portal frame structure; structural optimization; discrete variables
