Abstract
The architecture of modern structures requires the use of structural systems in a wide range of both geometric and topological forms. Spatial steel structures are one of the most varied, complex and demanded types of structural forms of coatings for buildings and construction structures. The method of constructing spatial lattice structures of a complex geometric shape considered in the article is based on automated methods of computer modeling of the shell surface and the subsequent development of a separate spatial cell of a lattice of a certain type - a "family". The structural cell of the lattice is the basis for the topological structure of the building system, which is created using special software. The result of this development is a digital model of the megastructure of the entire spatial structure. Subsequent export of the constructed geometry to computational software systems allows one to estimate the stress-strain state of the system and select the cross sections of all its elements. The methodology developed in the article makes it possible to quickly and accurately design spatial structural structures of coatings of an arbitrary geometric shape. The speed and accuracy of modeling and calculation of shell lattice structures is achieved by optimizing the sequence of application of modern programs, using special modeling techniques.
