From the standpoint of controlling the behavior of steel floor beams during the operation of a structure, the use of elastically compliant joints in the beam support nodes at the construction stage is considered. Elastic joints are an intermediate link between an ideal hinge and an absolutely rigid connection of the beam ends to the main load-bearing structures and can provide an effective structural solution for connecting elements of any materials with a real reduction in their stress-strain state. The use of resilient joints can be an effective solution for running roofs and ceilings, in load-bearing structures of steel frames, multi-span beam structures. This approach, in principle, is also applicable to beam structures of a through section.
