Answer #1

(a)

Single shear:

P=fv(0.785x1)

P=0.6x36x0.785=16.956 kips

(b)

Double shear=twice of single shear

double shear=33.912 kips

(c)

Fu=120 ksi for A325 bolts

Ft=0.75Fu

Ft=0.75x120=90

Capacity=0.75x90x0.785=53 kips

(d)

tb=1.0625 in

Lc=2-1.0625/2=1.46875 in

Capacity=0.75x1.2x1.46875x0.5x58=38.3 kips

(e)

tb=1+1/16=1.0625 in

Lc=3-1.0625=1.9375 in

Capacity=0.75x1.2x1.9375x0.5x58=50.65 kips

Limit=2.4dtFu=2.4x1x0.5x58=69.6 kips
