[提要] 對(duì)80m跨預(yù)應(yīng)力鋼屋架的端頭節(jié)點(diǎn)進(jìn)行了有限元彈性分析,了解了端頭節(jié)點(diǎn)的受力性能,并與試驗(yàn)結(jié)果進(jìn)行比較,結(jié)果較為吻合,為工程應(yīng)用作了初步探討。
[關(guān)鍵詞] 鋼屋架 端頭節(jié)點(diǎn) 預(yù)應(yīng)力 有限元分析This paper encompasses the finite element analysis of the endpoint of an 80-m prestressed roof girder to study the mechanical behavior of the endpoint. The comparison between the results of the analysis and those of the experiment is satisfactory. Thereby a preliminary research of application of this kind of structure is presented.
Keywords: steel structure; roof trusses; endpoint; prestress; finite element; stress
