摘要
对一栋位于台风区的超高层建筑的刚体模型进行了风洞试验 ,测量了该建筑物表面的平均风压和脉动风压 .在特定风向角下 ,建筑物的几个位置处出现较大的负压 ,不能满足设计要求 .在对建筑物局部外形进行修改之后 ,有效地减小了最大负压 ,满足了表面石材及玻璃幕墙的设计要求 .
A wind tunnel test on the rigid model of a super-tall building located in a typhoon zone is carried out to measure the mean and fluctuating wind pressure distributions on the building. Very large negative pressures at some measuring points are observed, which can not meet the limit of design code to the building enclosure material. Modifications on the local contour of the building reduce effectively the wind pressures at these dangerous points. The countermeasure for reducing local wind pressures of buildings may be used for reference in similar practical applications.
