$5$a$.$ Analyze the $30$ ft $.$ wall shown below for using strip reinforcement. The strips will be spaced at $s=3\mathrm{.}5ft.$ and $h=3\mathrm{.}5ft.$ on the concrete wall facing units. Interlocking reinforced concrete facing units, which are shaped as indicated, are $8$ in$.$ thick and weigh about $1$ ton each. A wall leveling footing will be poured to provide for level placement of the first course of panels. A $12-$in$.$ thick reinforced cap will be placed on top of the wall to maintain top alignment and appearance. Analyze a typical interior vertical section and select tension strips based on $f_y=38,000lb.\frac{?}{i{n}^2}$ and width of strip $=4in.$ Other data: $=34,=112lb\frac{.}{f}{t}^3,{}_u=24,FS(B)=3\mathrm{.}0$ and $F{S}_{(P)}=3\mathrm{.}0.$

$5$ b$.$ Check the bearing capacity for a unit width strip with a footing width $B($length of metal strips, not little leveling pad below wall$)$ depending on the strip configuration. Take all shape, depth, inclination factors $=1\mathrm{.}0.$
