［摘要］神農(nóng)大劇院建筑表面風(fēng)壓分布復(fù)雜。屋面的最大跨度達(dá)103m，主結(jié)構(gòu)屋面高度55m，屋頂上設(shè)有18m高的上懸挑幕墻及52個(gè)最高35m的裝飾架。在大跨度結(jié)構(gòu)上布置高柔的次結(jié)構(gòu)，風(fēng)荷載作用是結(jié)構(gòu)設(shè)計(jì)的關(guān)鍵。詳細(xì)介紹了神農(nóng)大劇院屋面上懸挑幕墻及裝飾架等高柔次結(jié)構(gòu)的設(shè)計(jì)，利用數(shù)值風(fēng)洞模擬及風(fēng)洞試驗(yàn)研究兩種方法對整體結(jié)構(gòu)及局部高柔次結(jié)構(gòu)的表面風(fēng)壓特性及風(fēng)致振動特性進(jìn)行了深入研究。

［關(guān)鍵詞］大跨空間鋼結(jié)構(gòu)；桁架；數(shù)值風(fēng)洞；風(fēng)洞試驗(yàn)；風(fēng)荷載

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
