[提要] 以廣西北海機(jī)場航站樓為工程實(shí)例，根據(jù)該工程的特殊性和復(fù)雜性，提出了整體分析和局部分析的有限元處理方法。研究表明，在拱頂節(jié)點(diǎn)的截面變化處出現(xiàn)明顯的應(yīng)力集中現(xiàn)象，說明了在大型結(jié)構(gòu)中為確保結(jié)構(gòu)的安全而進(jìn)行二次分析的重要性，分析方法可供工程設(shè)計(jì)及有關(guān)研究人員參考。
[關(guān)鍵詞] 整體分析 局部分析 應(yīng)力集中 有限單元法According to the complexity and particularity of the project, this paper presents a finite element method of both global analysis and local analysis for the airport building of Beihai. The research indicates that stress concentration will take place on the arch-top joint where section has an abrupt change, and it is important to carry out quadratic analysis to ensure the safety in the large structure. The analysis method has reference value for engineers and researchers.Keywords: global analysis; local analysis; stress concentration; FEM
