Abstract

Super-tall building may cause the severe pedestrian level wind problems. In past studies, the characteristics of pedestrian level wind around isolated super-tall building had been investigated. The maximum wind speed and high wind speed zones usually appeared near the corner of buildings. However, in practice, the super-tall building always has the podium for commercial and public services, such as shopping malls, parking lots and entertainment places. The podium may change the flow field near the ground around the super tall building. Thus, a series of wind-tunnel tests were carried out in this study to investigate the podium effects on pedestrian level wind around the super-tall buildings. It was found that the super-tall building with a low rise podium shown the better behaviour on pedestrian level wind than the isolated super-tall building.
