［摘要］以2008年奥运会羽毛球馆弦支穹顶结构为研究对象，对上部弦支穹顶、上下部整体结构两个计算模型进行结构自振特性分析、静力及抗震等方面的对比分析，重点研究了下部混凝土结构对上部屋盖钢结构的影响。分析结果表明，下部混凝土结构对上部弦支穹顶钢结构受力和变形有一定影响，尤其是在温度作用及地震作用下受力和变形差别较大。弦支穹顶结构设计应进行上下部结构共同工作分析，并可据此对屋盖钢结构进行优化设计。

Abstract:For the badminton gymnasium of 2008 Olympic Games, two computer structural models, the only upper suspended dome structure and the whole structure, were built to conduct modal analysis, static analysis and earthquake-resistance analysis and then to compare the results from the two models, focusing on the research of the impact of the lower reinforce concrete structure on the upper structural steel roof. As shown in the results, the lower reinforced concrete structure has a general impact on the upper structural steel suspended dome when it comes to the internal force and the deformation differences from the two models, subject to the temperature load and the seismic load each. As a result, the coincident work between the upper and lower structure should be considered, based on which the structural optimization design can be performed.

Keywords:suspended dome; coincident work; modal analysis; static analysis; earthquake-resistance analysis
