A comparative analysis of the results of numerical studies of the shear strength of the two most common models fragment joint compound reinforced concrete floor slab with a column of monolithic buildings with punching and heating. Simulation of stress-strain state of concrete samples conducted in LIRA 9.6 R9 with various combinations of loads and effects in the nonlinear formulation to study the processes of their destruction. Revealed new features of the stress-strain state of reinforced concrete monolithic buildings with bezrigelnym frame with an alternative design scheme that reflects the true picture of loading plate and corresponds to the method of Eurocode 2.

Keywords: connection node reinforced concrete slabs with a column, monolithic building with bezrigelnym frame, strength plates with cut and bursting under heat, non-linear analysis
