Determine the allowable moment $($using ASD procedures$)$ based on placing the

maximum size reinforcing bar that is permitted in an $8$ in$.$ CMU while still having the

neutral axis in the face shell.

Given:

face shell thickness $=1\mathrm{.}25in.$

$d=5\mathrm{.}3in.$

bar spacing $=24$ in$.$ o$.$c$.$

modular ratio $n=21\mathrm{.}48$ or $15\mathrm{.}5$

$Fs=32,000$ psi
