摘要
本文在进行了几何非线性有限元分析计算的基础上，设计了索穹顶结构的试验模型，采用模型计算、模型测试的对比方案进行模型结构试验研究。内容包括受压杆件的稳定性设计、节点设计、钢索锚固、模型架设过程中钢索的张拉工艺及张拉顺序等。然后，分别在预张状态和加载状态下对模型的拉索张力、屋顶垂度进行了测试，并与计算结果作了对比分析。
Based on the analysis with nonlinear finite element method, the authors designed a cable dome model and made an experiment analysis. The content included the design of compressional member, joint, cable connection and model construction. The tension and displacment in pretension and load status were measured and compared with theoretical results respectively.
