    Abstract. Method of calculation and the results of solving a number of problems for the joint of a flat beamless floor slab with a round column are presented. Some cases of loading - with different values of bending moments and without them, as well as variants of longitudinal reinforcement in compressed and stretched zones are considered. The results are compared with the data obtained by the refined calculation method based on the joint use of the nonlinear deformation model and the theory of strength and plasticity. The stress-strain state of the node was investigated, the characteristic isofields of stresses and deformations in the area of the junction of a round column with a plate for samples with and without bending moment in the column were obtained, the nature of the fracture and the bearing capacity of the node for punching were determined. It is established that the longitudinal compressed and stretched reinforcement, as well as the bending moment in the column affect the limit value of the punching force.
    Key words: bearing capacity of flat slab for punching, nonlinear deformation model, strength and plasticity theory, bending moment in column, longitudinal reinforcement, dowel effect, inclined sections, finite element method, shear deformations.
