Problem $5\mathrm{.}12$

Analysis of T Beams

For Problems $5\mathrm{.}5$ to $5\mathrm{.}15,$ determine the design moment strengths

$M_n$ of the sections shown. Use $f_y=60,000$ and $f_c^{\text{'}}=4000$ psi,

except for Problem $5\mathrm{.}9,$ where $f_c^{\text{'}}=5000$ psi. Check each section

to see if it is ductile.
