条形钢拉板索穹顶结构形态研究

The Research of Strip Tensile Steel Plate Cable Dome

在索穹顶结构的基础上,提出将上弦柔性拉索换成预应力条形钢拉板带,形成一种新型钢拉板索穹顶结构。以投影为正八边形的钢拉板索穹顶结构为例,对计算模型进行预应力设计和静力性能分析,验证了该体系的可行性与合理性;并设计制作了一个缩尺模型。

On the basis of cable dome, a new structure of strip tensile steel plate cable dome is presented which uses prestressed tensile steel plate band in place of top chord cable.In this thesis, a strip tensile steel plate whose projection is a regular octagon is simulated in the analysis of the calculation model, which verifies the feasibility and reasonability of the new structure.Besides, a scale model is designed and manufactured in this paper.
