Problem $1$

$-$ Footing supporting a retaining wall.

$-$ Grade $60$ uncoated reinforcement.

$-3000$ psi NWC

Determine the minimum clear cover dimensions A $,$ B $,$ and C $.$

Determine the standard $90$ deg. hook dimension at the bottom of the wall vertical reinforcement.

Determine dimension D$.$

The dimension, E$,$ is approximately $13$ in $.$

Determine whether this is long enough to develop the $\backslash$#$4$@$12"$ vertical reinforcement.
