The purpose of the work is to determine the most accurate and at the same time rational methods of modeling the work of building structures. Research methods - modeling of building structures using universal software packages, laboratory experiment, processing and analysis of the results. The real pliability of the joints of metal structures, in particular the joints of the beams to the columns of steel frames. Nodes of various constructive decisions, including, at at local damages of designs were considered. It is proved that in all such cases the actual operation of the connection nodes can differ significantly from their idealized models (hinge, rigid connection, etc.). When considering examples of reinforcement of metal structures of buildings associated with the choice of correct design models, it was concluded that the study of complex building structures should begin with a detailed analysis of the object, working conditions and functional purpose of the object, analysis of functional relationships and features of the individual elements of a complex object for the possible decomposition of a complex system into several simpler subsystems. Then the calculation problems are formulated, the adequacy of the general calculation model and separate subsystems is checked. A method for testing the resistance of buildings to progressive destruction was proposed. At the initial stage of design, the main measure is to develop such a structural scheme of the building, which provides its spatial rigidity in case of emergency. Next you need to find the most vulnerable and important in terms of structural elements and consider the most dangerous calculation schemes of local destruction.
