Stress-Strain State of the Fragments of Armored Monolithic Floors with Tubular Inserts

The stress-strain state of fragments of an armored floor with tubular inserts is determined with regard for the nonlinearity of deformation of concrete according to SBN V.2.6-98:2009. The applied technique allows us to compute the deflections of the floor depending on the nature of loading and deformation. The comparison of the theoretical and experimental values of the deflections of fragments cut out from the armored floor with unidirectional arrangement of polystyrene inserts with rectangular cross sections reveals their close proximity.
