The article is devoted to the investigation of the stress-strain state of concrete samples made by the method of layering extrusion of a concrete mixture. Additive production is an innovative solution for the erection of building structures and therefore the issue of studying the actual operation of «printed» structures and their computation is very relevant. In the course of the study, a comparison between the results of laboratory tests of samples and the results of computer simulation of the work of a fragment of a bearing vertical building structure was made.
