大跨度矩形钢管单层球壳钢结构应用与研究

Application and research of large-span rectangular steel tube single layer ball steel structure

采用理论分析软件与缩尺模型实验相结合,对大直径矩形钢管单层钢球壳体结构进行了分析研究,并对理论计算结果与试验数据结果进行了对比,表明二者得到的数据基本吻合,结构几何非线性对整体稳定性有重要作用。

Adopting the combination of theoretical analyzing software and shrinking model experiment, big diameter steel tube single layer ball steel structure is discussed and analyzed in this article. It also compares the theoretical calculation result with experimental data result, shows these two results are basically identical, and non-lineal structural geometry is important to the stability in whole.
