Some problems of determining the wind load on lattice spatial structures

Abstract

The article discusses the problems of determining the wind load on lattice spatial structures. The provisions of Russian standards in the field of construction, electrical installa-tions and mechanical engineering, as well as European standards, regarding the regulation of wind loads, the assignment of aerodynamic coefficients and recommendations for the transi-tion from wind pressure to loads on lattice structures are analyzed. It was revealed that there are significant differences in the regulation of wind loads in Russian standards in the field of construction and in the field of electrical installations; The standards in the field of mechani-cal engineering have more preciseinstructions on the assignment of aerodynamic drag coefficients for profile-section rods than the standards in the construction field. It is shown that the methodology for determining the wind load on lattice structures is mainly focused on the use of simplified design schemes and requires improvement for use of spatial design schemes.
