Abstract
This study investigates the pressure acting on a low-rise building roof and its surrounding wind speed, based on the full-scale measurement during the passage of TY202116. The pressure was measured with a new measurement system developed by the author’s research team. The analysis of the pressure acting on the roof together with the wind speed nearby shows strong non-stationarity; negative peak of the pressure as well as gusty wind occur in clusters, illustrating difference in characteristics compared to the inflow wind and wind pressure commonly assumed in wind tunnel experiments and wind resistant design for tall buildings. This observation calls for further investigation of wind load acting on low-rise buildings, in order to better understand the mechanism of their damages and to evaluate wind induced risk for such buildings.
