Purpose. The purpose of this study is to increase the strength, stability and safe operation of outdoor advertising structures (billboards) based on the modern ANSYS engineering modeling software package.
Methods. To create a digital model of the design, an integrated approach was applied, combining the stages of geometric construction and engineering calculation. The original geometry was created in Autodesk Inventor Professional CAD system. ANSYS module was used for strength and dynamic calculations.
Findings. Complex modeling in the ANSYS environment made it possible to obtain results characterizing the behavior of the billboard design under design loads. It was found that at an incoming flow speed of 23 m/s, the average integral aerodynamic pressure on the plane of a standard size board of 3x6 m is 340 Pa. Visualization of the pressure and velocity fields confirmed the formation of a classic picture of the flow around a flat obstacle, a high pressure zone on the windward side and a turbulent rarefaction zone with vortex formation on the leeward side and on the sides of the structure. The resulting wind load is determined, which for this area is 6.1 kN.
Application field of research. The model is the basis for the development of reasonable smooth repair and maintenance, predicting the residual life of structures. On the basis of modeling, it is possible to develop a program for point instrumental control of specific critical nodes.
