［摘要］神农大剧院建筑表面风压分布复杂。屋面的最大跨度达103m，主结构屋面高度55m，屋顶上设有18m高的上悬挑幕墙及52个最高35m的装饰架。在大跨度结构上布置高柔的次结构，风荷载作用是结构设计的关键。详细介绍了神农大剧院屋面上悬挑幕墙及装饰架等高柔次结构的设计，利用数值风洞模拟及风洞试验研究两种方法对整体结构及局部高柔次结构的表面风压特性及风致振动特性进行了深入研究。

Abstract: The wind pressure distribution on the surface of Shennong Theatre is very complicated. The main roof has the largest span of 103 meters and a height of 55 meters. A large area curtain wall with a height of 18 meters stands on the roof. 52 decoration bars with the highest of 35 meters from the roof are attached on the outer curtain wall. Both the main structure and the attached secondary decoration structure are wind sensitive structures due to their soft stiffness. The design of wind resistance in such structures is challenged. Structural design of the secondary decoration structures has been introduced in detail. The static and dynamic effects of wind on both the main and the secondary structures were investigated by a numerical wind tunnel study and by a wind tunnel test as well in this research.

Keywords: long-span spatial steel structure; truss; numerical wind tunnel; wind tunnel test; wind load
