Annotation: This article discusses the interface node of a pipe-concrete column of circular cross section with a diameter of 220 mm. and a thick metal wall of 7 mm, the length of the column fragment 1050 mm. The pipe is filled with concrete grade B15. As crossbars, a steel beam of an I-section (20B1) 1100 mm long is considered. The joining of the crossbars to the column is provided by two horizontal and 4 vertical overlays 5 mm thick. by welding. In the LIRA-SAPR 2017 software package, a model of this unit was created and the maximum normal stresses at the joints of the junction of the crossbar to the column were determined. The study was conducted on two models: a model with concrete and pipe working together; а model with concrete slipping inside a steel pipe. That allowed determining the efficiency of this node.
Keywords: pipe-concrete column mating unit, longitudinal force, pipe-concrete element, joint work of concrete core and steel shell, concentration of materials, concentration of maximum stresses at joints, calculation of normal stresses, zones with the highest normal stresses.
