鲁台经贸中心-会展中心蒙皮采用大跨度复杂空间钢网壳结构,包括双层网壳和单层网壳,其稳定分析是结构设计的重点和难点。本文分别研究了局部单层网壳结构和整体网壳结构在多种不利荷载组合作用下的稳定性能,分析过程中考虑几何非线性、初始缺陷以及雪荷载不均匀布置的影响。分析结果表明,网壳结构具有良好的整体稳定性能。
Lutai Economic and Trade Center - Exhibition Center skin using large-span complex space steel reticulated shell structure, including double-layer reticulated shell and single-layer reticulated shell, the stability analysis of the structural design is the focus and difficulty. In this paper, the stability of the local single-layer reticulated shell structure and the whole reticulated shell structure under various unfavorable load combinations are studied respectively. The influences of geometrical nonlinearity, initial defects and non-uniform snow load placement are considered in the analysis. The analysis results show that the reticulated shell structure has a good overall stability.
