There was carried out a study of the wind effect on various types of vertical steel tanks in various configurations for the purpose of possible adjustment of regulatory documents. In the course of the work, the most common types of large-sized tanks were selected, it was determined that the most common layout of tanks was 2 per group, none of the considered enterprises observed the distance between tanks (3d) regulated by regulatory documents, at which it is permissible to assign a wind load based on aerodynamic coefficients in regulatory documents. For the selected eight layouts of vertical steel tanks, physical modeling of wind effects was performed in a wind tunnel. As a result of the conducted series of tests, the main parameters of the tanks and their arrangement schemes in groups were identified, which affect the distribution of aerodynamic coefficients of external pressure over their surface. Based on the results of the studies, it is proposed to introduce the parameter of the ratio of the tank diameter to its height d/h to assess wind effects on groups of tanks.
