摘 要: 本文在对网架屋盖、斜拉索和塔柱作整体分析的基础上,根据有限元的基本原理,通过斜拉索和塔柱的简化,考虑塔柱的弹性支承作用,并按照施工步骤分三个阶段来研究整个屋盖结构的静力和动力特性以及各种结构参数的影响,得出了一些对工程有益的结论。 Abstract Based on an overall analysis of the space truss roof, cables and tower columns, and in accordance with the principles of finite element method, this paper simplifies the models of suspended cables and tower columns, takes into account the elastic support of tower columns and studies the static and dynamic characteristic of the whole roof as well as influence of various structural parameters in three stages according to the construction sequence. Finally some useful suggestions for practical engineering have been presented.
