[提要] 利用風洞試驗對寧波國際會展中心的大跨度屋蓋及建筑外墻在各種風向角下的風壓分布情況進行了測試，考察了展廳在開門與閉門時風壓的變化情況、不同風速對建筑表面風壓系數(shù)的影響以及相鄰建筑對屋蓋風荷載的影響等。
[關(guān)鍵詞] 大跨度結(jié)構(gòu) 圓柱殼屋蓋 平頂屋蓋 風洞試驗 風壓系數(shù)The behavior of wind-pressure distribution on the roofs and cladding walls of Ningbo International Conference & Exhibition Center in different wind directions has been investigated though an l:160 model wind tunnel test. The variations of internal and external air pressure of main exhibition hall are measured when the exterior doors open or close, the wind pressure coefficients on the surface of buildings under different wind velocities are studied, and the phenomenon that wind loads can be modified by the placement and configuration of adjacent buildings are considered.
Keywords: large span structure; cylindrical roof; plane roof; wind tunnel test; wind pressure coefficient
