$**$SHOW THE SOLUTION$**$

Situation $5$: The $13mm$ thick plates of the lap

joint shown is made of A$36$ steel whose yield

strength and tensile strength is $248$MPa and

$400$MPa, respectively. The bolts are A$325-$

M$22.$ The holes are standard sizes and the

threads are excluded from the shear plane.

Assume that deformation at bolt holes is a

design consideration.

Determine the nominal strength of the lap

joint based on bearing strength $(kN)$ of the

bolts on the plate.

a$.1185kN$

c$.1335kN$

b$.,1098kN$

d$.1272kN$

Determine the design $($LRFD$)$ strength of the

lap joint based on bearing strength $(kN)$ of

the polts on the plate.

d$.888$

Determine the nominal strength of the lap

joint based on shear strength $(kN)$ of the

bolts.

c$.566$

b$.695$

d$.521$

Determine the allowable $($ASD$)$ strength of

the lap joint based on shear strength $($kN$)$ of

the bolts.
