A T$-$beam for a floor system has a slab thickness of $75mm$ and a web thickness of $375mm.$ It

has an effective depth of $600mm.$ It is reinforced with a steel area of $6904m{m}^2.$ If the $t$ beam

clear span is equal to $5\mathrm{.}40m$ and the beam adjacent spacing center to center is $1\mathrm{.}8m,$ solve

for the ultimate moment capacity. fc $20\mathrm{.}7$MPa, fy$=344\mathrm{.}70$ MPa.
