上海铁路南站屋盖结构风致响应研究

随着建筑科技和施工工艺的逐渐进步,大量形式新颖、质量轻、柔性大的大跨度屋面不断涌现,这些结构形式丰富多彩,且采用了许多新材料和新技术,发展了许多新的空间结构形式.正在建设的上海铁路南站是其中之一.但大跨度屋盖结构因具有质量轻、柔性大、阻尼小等特点,风荷载是其结构设计的控制荷载.通过对铁路南站站屋屋盖风洞试验和有限元分析,得出的结论供结构设计研究,在建设过程中取得良好的结果.

Wind Response Research on Roof Structure of Shanghai South Railway Station

With the development of building technology and techniques,more and more new types of large-span roof structures comes out,they are light,flexible and colorful.Many new space structures are being developed by means of using new materials and technologies.And Shanghai South Railway Station being built is one of these new structures.But large-span structures have the characteristics of low gravity,large flexibility and low damp.Wind load is the key to structure design.Results are acquired by wind tunnel test on model of Shanghai South Railway Station,and analysis with the ANSYS,The tests results can be used as references for roof structure design,and the production of Shanghai South Railway Station built is being achieved.
