Abstract
In recent decades, high-rise construction has been actively developing in the Russian Federation. This led to a significant increase in aerodynamic studies of high-altitude objects in accordance with the methodology of SP 20.13330.2016 «SNiP 2.01.07-85* Loads and Impacts». In many domestic and foreign works, when conducting such studies, the step in the azimuth angle of the wind flow is 15 degrees (less often 20 degrees). This paper presents results that show that such a wind azimuth step, in conditions of dense multi-height buildings, results in a significant underestimation of local negative peak wind loads. The question of sufficiency of the wind flow azimuth step of 5 degrees is discussed.
