Annotation: The paper presents a simulation method and analysis of the stress-strain state of the junction of a load-bearing reinforced concrete wall with a powerful beam. The calculations were performed taking into account the physical nonlinearity. The stress-strain properties of concrete are described by the method adopted in the Lyra-SAPR software package using modified deformation diagrams in the unaxial state. To select such a scheme of a finite element model, which ensures a sufficient degree of adequacy of the calculation results, three variants of the scheme are considered: they are from flat elements; flat elements with an absolutely rigid insert imitating a wall section within the contour of the support section of the beam; bulk items. In numerical studies, the effect of the size of the beam, the classes of concrete and reinforcement on the bearing capacity of a fragment of a reinforced concrete wall was evaluated. The nature of the stress state of the wall in the zone of the beam is described.
Keywords: a digester, temperature regime, heat and mass exchange, heat transfer intensity, heat-emission, bubblereinforced concrete, powerful beam, finite element model, stresses, deformations, detailed modeling.
