rods Ø18 or 20 mm made of steel of class A-Sh, grade 35GS, the yield point of which ranged
from 415 to 490 MPa, the ultimate strength from 610 to 760 MPa. Some of the beams did not
have transverse reinforcement, others were reinforced with vertical welded clamps made of
reinforcing wire Ø 6 mm of class A-1, grade St3sp3 with a pitch of 8-10 cm. / 3h (20 cm) on one
half of the beam length. To determine the strength and deformation properties of concrete at
normal temperature and when heated, cubes 10x10x10 cm and prisms 10x10x10 cm were
concreted simultaneously with the beams.
