Abstract

<p>Large-eddy simulation (LES) was conducted to analyze the flow around an isolated building model in an urban boundary layer. Based on the LES results, gust factor (GF) and peak factor (PF) at the pedestrian level were analyzed. Although the mean wind speed was highest in the vicinity of the building corner on the upstream side, GF and PF were relatively small at that point. The statistical uncertainty of GF tends to decrease with increasing mean wind speed. However, that of PF shows similar magnitude at any point and has no clear relationship with the wind speed.</p>
