Wind Environment Test of Pedestrian Level Around a Highrise Building/Fan Youjing,Li Huizhi,Wu Yizhang(College of Civil Engineering,Zhengzhou University,Zhengzhou 450002,China)
Abstract:The pedestrian level wind environment around a highrise building at 16 wind incidences is investigated by a 1∶300 model test in wind tunnel.The probability of wind comfort of sitting,standing and walking at 26 positions is predicted by combining historical wind data with wind tunnel test.According to the test results,suggestion and measure to improving wind environment of some areas are presented.
