泉州中芸洲海景花园建筑群体的干扰效应研究

制作了缩尺比为1∶200的泉州中芸洲海景花园9栋高层建筑的刚性模型,在其外表面布置足够的测点进行了同步测压风洞试验。试验得到了该9栋高层建筑表面的平均风压系数和脉动风压系数。利用风洞试验得到的风荷载数据,研究了该9栋建筑的风致响应,包括位移和加速度响应。结果表明:左右或下游建筑的影响可能会增大上游建筑的背风面"吸力";泉州中芸洲海景花园9栋高层建筑相互干扰效应主要表现为"遮挡"效应,其顶部加速度响应均小于规范限值,能满足人体舒适度的相关要求。

Investigation of wind-induced interference effects on tall buildings of Quanzhou Zhongyunzhou International Seascape Garden

A rigid model of Quanzhou Zhongyunzhou International Seascape Garden including 9 tall buildings was built with a scale of 1∶200,and adequate pressure taps were arranged on the external surface of these buildings.A wind tunnel test was carried out to obtain the wind loads on them.And then wind-induced responses of these 9 tall buildings,including displacement and acceleration,were analyzed using the wind loads obtained by wind tunnel test.The results show that the suction wind force on leeward wall of a building may be magnified by the effects of parallel or downstream buildings.For the 9 high-rise buildings of Quanzhou Zhongyunzhou International Seascape Garden,the interferences among them mainly exhibit the "sheltering" effects.The accelerations of the 9 high-rise buildings are smaller than the specified in Chinese Code,so the demand of body comfort can be satisfied.
