W355313.6 A36 hot rolled sections were used for the experi-
ments. A uniaxial tension test was performed on seven dog-bone
specimens with a gauge length of 125 mm, a gauge width of 25
mm, and a thickness of 9.5 and 6.4 mm cut from flanges and the
web, respectively. Average yield strengths of 354.9 and 381.9
MPa, moduli of elasticity of 198.3 and 177.5 GPa, and Poisson’s
ratios of 0.305 and 0.299 were obtained from the specimens cut
from the flange and web, respectively. A typical stress-strain plot
for the flange in uniaxial tension test is shown in Fig. 1~a!. The
minimum reinforcement in concrete slabs for temperature and
shrinkage was provided by using a 150 315036.4 mm welded
smooth wire mesh.
