Modeling of Units of Cable-Stayed Coverings of Sports Facilities

The article is devoted to modeling of nodes of cable-stayed coverings of sports facilities. In recent decades, cable-stayed systems have been increasingly used in the construction of large-span structures, including sports complexes. Stadiums and sports complexes built on the territory of new modern micro-districts become centers of attraction for urban residents, play a special role in the renewal and revitalization of the urban environment. The advantages of cable-stayed systems are the possibility of reducing the number of frame supports, reducing the cost of installation and transportation work, reducing construction time, and using less metal. This makes it possible to reduce construction costs and improve the economic efficiency of the project. However, the use of enclosed ropes, subject to corrosion and material fatigue, in cable-stayed systems can lead to unexpected failure of the system. The solution may be to use open ropes. The article highlights the advantages of cable-stayed systems, considers perspective directions of their designing with the use of solid-state modeling methods. The creation of digital models makes it possible to evaluate the effect of elongation and skew of the cables, take into account the longitudinal force that occurs in the beam element, temperature changes, compare various options for constructive solutions for fastening the cables to beam elements and pylons. The authors consider various types of cable-stayed coating nodes and propose methods for their modeling.
