P$4\mathrm{.}48$

A$572$ Grade $50$ steel and $\frac{7}{8}$ in$.$ bolts are used in the

bolted splice shown in Figure P$4\mathrm{.}48.$ Consider yield, net

section rupture, and block shear rupture. Determine the

$($a$)$ design strength by LRFD and $($b$)$ the allowable

strength by ASD.

answer shoul be design strength $=491$ k
