Example $1$

Select a beam size and bars using ACI strength method of the beam ABCD shown in figure. $f{c}^{\text{'}}=30$MPa;$fy=400$ MPa.$W_{DL}=44k\frac{N}{m}$;$W_{LL}=50k\frac{N}{m}.\frac{d}{b}=1\mathrm{.}5.$ Use $=(0\mathrm{.}3-0\mathrm{.}5){}_{\text{m}\text{a}\text{x}}.$ Check $h_{\text{m}\text{i}\text{n}},$ from deflection considerations using ACI Table $9\mathrm{.}5($a$).$ Use $75mm.$ effective cover.
