$10\mathrm{.}10$ Given: The elevation view of the two$-$story wood$-$frame shearwall in Figure $10.$C$.$ The

wind force reactions from the roof diaphragm and second$-$floor diaphragm are

shown in the sketch. Vertical loads carried by the wall are also shown in the

sketch $($dead load values include the weight of the wall$).$ Wall sheathing is $\frac{15}{{32}^{-}}$

in$.$ STRUCTURAL I with $8$d common or galvanized box nails.

GRAVTY LOADS TO WALL

ROOF D $=165$ LBMFT

ROOF L $=200L\frac{B}{F}T$

FLOOR D $=250$ LB$/$FT

FLOOR L $=500$ LB$/$FT

FIGURE $10.$C

Find: $,a.$ The required nailing for the shear segment. Give full specifications.

b$.$ The required collector forces for the connections at $A,B,C,$ and $D.$

c$.$ The net design uplift force for the tension chord at the first$-$ and second$-$floor

levels.

d$.$ The maximum force in the compression chord at the first$-$ and second$-$floor

levels. Consider the effects of both gravity loads and lateral forces. Assume

that the header is supported by the shear segment chord.

e$.$ If the adjusted design value, $Z^{\text{'}},$ on one anchor bolt is $1500lb,$ determine the

number and approximate spacing of anchor bolts necessary to transfer the

shear from bottom wall plate to the foundation. These bolts are in addition to

those required for uplift.
