Abstract
. In an urban area where middle and high-height buildings are densely built on a complex terrain, it is important for wind-resistant design to know what kind of strong wind blows during a typhoon and the wind pressure acts on the building. In this study, we focused on the wind of the wind direction SSE observed during typhoon LAN (2017), and investigated the relationship between the topography and the flow field around the buildings, and the wall surface pressure by LES. As a result, we clarified the complicated flow due to the interference between the target building and the local terrain and surrounding buildings. In addition, the validity was shown by comparing the wind pressure coefficient of LES with that of the wind tunnel experiment.
