The article presents the results of studying the stress-strain state of the elements of the connection node of translucent modules with a load-bearing frame as part of a standard post-and-crossbar facade system. The research is aimed at studying the initial stresses and deformations of the system node elements in its design position without applying external loads. At the initial stage, experimental studies were conducted to determine the elastic modulus of rubber inserts, which are the main elements that transmit forces from translucent modules to the supporting frame of the system. Based on the results of the tests, an approximated graph of the dependence of stresses on deformations of rubber inserts was obtained, which was exported to the software package, for modeling their actual work when calculating by finite element methods. At the stage of numerical studies geometrically and physically nonlinear problems of contact interaction of elements were solved, the resulting picture of the stress-strain state of the node in position before the application of loads and impacts was created, the value of compression of the external pressure profile to the load-bearing frame was set.
