Determination of Aerodynamic Coefficients in the Design of Buildings

The article considers the variable definition of wind loads on a building. In order to determine the wind load on the building, various options for setting the wind load were considered, taking into account the standards of various countries. 4 schemes were considered. The first and second determination schemes are carried out taking into account the provisions of the Russian standard SP 20.13330.2016, the third and fourth schemes in accordance with the Load Code for The Design Of Building Structures, GBJ 9–87. As amended by GB 50,009–2001 from 2006. To select the load application scheme in the design model of the building, the total (for the entire length) aerodynamic coefficient in the direction of the vertical axis was determined. According to the results of the study, the scheme of action of the wind load corresponding to the highest load value was determined. It is also noted that more accurate aerodynamic coefficients can be obtained from the results of model aerodynamic tests conducted in a wind tunnel.
