应用张力补偿法和逆迭代法对大跨弦支穹顶结构进行形态分析,通过与相关工程数据对比,验证了本文结构形态分析方法的有效性.对考虑或不考虑上部单层网壳结构的下部张拉体系形态分析方法的计算效率和精度进行了对比,给出针对弦支穹顶结构形态分析步骤的建议,并分析了自重及固有恒载对结构找力结果的影响.研究发现,可以仅对下部张拉体系进行找力分析,结构自重对找力结果影响较大.
The tension compensation method and inverse iteration method are applied to the morphological analysis of the large-span suspen-dome structure, and the validity of the method of structural morphological analysis is verified by comparison with the relevant engineering data.For the purpose of considering or not considering the lower part of the upper monolayer reticulated shell structure The comparison between the computational efficiency and the precision of the morphological analysis method for tension system gives the suggestions for the morphological analysis of the suspen-dome structure, and analyzes the influence of self-weight and inherent constant load on the results of structural force search. The lower part of the tension system to find force analysis, structural weight on the search results have a greater impact.
