The paper considers the question of substantiating the choice of criteria for limiting states of monolithic reinforced concrete bearing systems for the regime of progressive collapse. Based on the results of computational and theoretical studies, structural elements and structural units of monolithic reinforced concrete buildings are determined, the destruction of which occurs first of all in the event of a failure of the vertical bearing structure. It is established that the destruction of such structural units and structural elements leads to the initialization of the process of progressive collapse. A computational and theoretical analysis has been performed to determine the ultimate deformation effects or load values according to the criteria for the bearing capacity of crutial units of monolithic reinforced concrete systems with different span sizes. It is established that as a basic criterion for estimating the stress-and-strain state of monolithic reinforced concrete structures for the mode of failure of a vertical bearing structure, the relative deformation amount corresponding to the formation of the “fracture” zone of the retaining section of the overlap under the action of transverse forces can be adopted.
