Problem $4\mathrm{.}9$

Compute the maximum service load $P$ causing

eccentric shear on the connection of the accompa$-$

nying figure. The loading is $25\%$ dead load and

$75\%$ live load. The bolts are $\frac{7}{8}-$in$.-$diam A $325$ bolts

in a bearing$-$type connection $($A$325-$X$)$ with

threads excluded from the shear plane. Assume the

bracket plate has adequate strength.

$(8)$ Use the elastic $($vector$)$ method.

$($b$)$ Use the strength method with rotation about

the instantaneous center.

$($c$)$ Use AISC Manual Tables $7-7$ to $7-14,$ with

interpolation.
