广西北海市机场航站楼整体及局部分析研究

Global and Local Analysis on the Airport Building in Beihai of Guangxi

以广西北海机场航站楼为工程实例 ,根据该工程的特殊性和复杂性 ,提出了整体分析和局部分析的有限元处理方法。研究表明 ,在拱顶节点的截面变化处出现明显的应力集中现象 ,说明了在大型结构中为确保结构的安全而进行二次分析的重要性 ,分析方法可供工程设计及有关研究人员参考。

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.
