航站楼建筑结构体系若干问题的探讨

Discussion on Some Problems of Structural Systems forAirport Terminal Buildings

因工作关系接触了许多机场航站楼,笔者将接触到的这些航站楼进行适当的对比和分类,找出了部分有共性的问题。通过对比发现,针对一些十分类似的问题不同的工程采取了不同的处理手法,如三角形管桁架间有的设有连系桁架而有的未设;索拱体系中有的采用了下垂曲线索而有的采用了上挠曲线索等。为弄清问题的本质,本文对这些问题分别从结构体系构成和优化分析等方面进行了分析,有利于更清楚地了解和认识航站楼建筑的设计,对今后的设计会有一定的帮助。

We visited many airport terminal buildings because of work. These airport terminal buildings were selected for appropriate comparison and classification to reveal some common problems. By contrast, we found that some very similar problems in different projects were dealt with using different ways. Such as some triangular tube truss had copular truss while some had not or some cable arch system used sagging curve cable while some used bogging curve cable. This article analyzed these problems in terms of structural system composition and optimization to understand the nature of the design of the terminal buildings. We believe this discussion will be certainly helpful for the future design.
