The article presents information about the
changes made to the code of rules for the
design of concrete structures reinforced with
polymer composite reinforcement. New rules
for the formation of relative deformations at
the base point of a two-line diagram of concrete
under axial tension, used to calculate
reinforced concrete elements for the second
group of limit states, are described. The rules
for calculating re-reinforced structures of
T-or I-beam cross-sections with a shelf in a
compressed zone by the method of limiting
forces are presented. The rules for taking into
account the inelastic properties of concrete of
the stretched zone when determining the elastic-
plastic moment of resistance for the extreme
stretched fibre of concrete with a rectangular
cross-section and a T-shape with a shelf
located in the compressed zone are clarified.
