Any structure must meet the technical requirements and still be optimal for the calculation. The aim of this article is to examine the surrogate modeling as a way to reduce labor costs in the calculation of the system, as well as the most accurate results, do not reduce the reliability parameters. The article deals with software systems that allow the calculations, examples of the use of surrogate modeling in various sectors and analysis of optimization of building structures such as steel trusses. Thus, surrogate modeling for the construction is a new and promising trend deserving more detailed study, opening up broad prospects optimization of various building structures.
