Characteristics of pedestrian-level wind around super-tall buildings with various configurations
AbstractSuper-tall buildings with unconventional configurations have been constructed all over the world, because of the social demand for more iconic buildings, better aerodynamic performance and/or for architectural aesthetic reasons. The aerodynamic characteristics of various super-tall building configurations have been studied by Tamura et al. (2010, 2011). However, there is also a need to study pedestrian-level winds around super-tall buildings with various unconventional configurations. These have not been studied well, although pedestrian-level winds around tall buildings with conventional rectangular-plan up to 200m high have been studied intensively. In this study, a series of wind-tunnel tests were carried out to investigate pedestrian-level winds around 40 super-tall building models with various configurations, including basic models, tapered models, corner-modified models, opening models, helical models, tilted models, composite models, triangular models, and polygonal models, corresponding to the cases in Tamura et al. (2010, 2011). The results of these tests have led to comprehensive discussions on pedestrian-level-wind characteristics of various super-tall building configurations under the condition of “same height and same volume”. It was found that super-tall buildings (400m in this study) provide much higher speed-up ratios at the pedestrian level than 200m-high buildings. The projected building widths, especially in the lower part, were found to significantly affect pedestrian-level winds.
