Many elements meet in nodes of spatial lattice structures. The node of such structure works in a complicated stressed state. Experimental methods traditionally used for assessment of the stress-strain state of nodals connections, give only approximate results, and for structures with complex geometry are generally useless. It is possible to study a distribution of stresses inside the nodal connector, which is a massive body, using calculation software packages. As a result of calculation of a model of nodal connection in the CosmosWorks environment, stresses both on the connector’s surface and inside of it were obtained. The authors carried out the research of a stress-strain state of the MArchI (Moscow Institute of Architecture) system node and performed the analysis of the level of surface stresses and stresses inside the nodal connector. On the basis of the fulfilled research, conclusions on the work of the nodal connector were drawn: stresses on the connector’s surface do not generally exceed the conventional yield strength of steel; maximum values thereof are observed on the reference plane and at points of contact of a nut and the connector; distribution of material for the given geometry of connector turned out to be rational; it is possible to reduce the volume of steel for the nodal connector by way of changing its conceptual design, for example, having considered the issue of formation of the node out of a hollow shell.
