| 摘 要： | 在鄂尔多斯东胜体育中心综合体育馆展厅结构设计中,提出了在张弦桁架之间设置双层网壳的新结构体系,在满足复杂建筑造型的同时,有效增加了结构的刚度和稳定性.设计了接近实际工程的基本算例,从整体模型入手,全面分析了垂跨比、初始预应力和撑杆数量变化对结构静力性能、动力性能以及用钢量的影响.依据分析结果,对不规则造型的鄂尔多斯东胜体育中心综合体育馆展厅进行设计,其中索的预应力是设计中的难点和关键,本文给出了详尽的调索方法和依据.

| Abstract: | A new hybrid structure arranging a double-layer shell between truss strings was proposed in the project-roof design of the Exhibition Center in Erdos Dong-sheng Sports Center.The new structure system not only meets the demand of adapting to an irregular large-span roof,but also increases the structural stiffness and stability.Model examples close to the actual project was designed.The effects of sag-to-span ratio,initial prestresses and the numbers of struts on the static and dynamic behaviors and the steel... |
