Pedestrian Wind Comfort around the Reinforced-Concrete Atypical Structure

Abstract

The high-rise buildings in built-up areas affect the surrounding pedestrian-level wind environment. Unpleasant gust strong wind especially between the buildings, on corners, the crossing points and passages, will experience these locations as not comfortable or dangerous. The series of parametric wind tunnel studies were carried out to investigate the effects of building width, height and the gap width between buildings on the pedestrian-level wind environment. In the article, we will discuss build up area around designed reinforced concrete structure with atypical shape - TWIN CITY A1 Bratislava (developer company: HB Reavis). We indicated the high wind speed areas for discomfort under strong wind conditions experimentally in BLWT wind tunnel and using CFD simulation. It is important to note that the wind effects applied on the reinforced-concrete structures and occurring around these structures are one of the most important input parameters in their design. Therefore, they should not be neglected. As it was mentioned above, this paper deals only with the wind effects occurring around the examined structure. The wind effects applied on the structure – determination of the external wind pressure coefficients, were discussed in [1].
