[提要]  利用风洞试验对宁波国际会展中心的大跨度屋盖及建筑外墙在各种风向角下的风压分布情况进行了测试，考察了展厅在开门与闭门时风压的变化情况、不同风速对建筑表面风压系数的影响以及相邻建筑对屋盖风荷载的影响等。

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.
