WELD:

 Weld Requirements:

At shear only case: 
Weld Length for shear, Lv = 14.50 in.
Shear Load per inch per weld, fv = R/Lv/2 = 20.00 / 14.50 / 2 = 0.69 kips/in/ weld 
theta = 0 deg.
cPhi  = 1.0 + 0.5 * sin(0)^1.5 = 1.00
Weld Coefficient = 0.60 * 70.00 * 1.00 * 1.00 * (2^0.5/2)*(1/16) = 1.86
Required weld size, Dv = fv/ (phi * coeff) = 0.69 / (0.75 * 1.86) = 0.50/16

Minimum fillet weld size : 
   At shear only load case = 0.03 in.
   per Table J2.4     = 0.19 in.
   5/8tp              = 0.23 in.
   user preference    = 0.25 in.

Dmax1 (using eqn 9-3)
 = tshpl * Fushpl / ( Fexx * C1 * 0.09)
 = 0.38 * 65.00 / ( 70.00 * 1.00 * 0.09 ) 
 = 3.94 
Dmax2 (using eqn 9-3)
 = twbm * Fusupport / ( Fexx * C1 * 0.09 )
 = 0.41 * 65.00 / ( 70.00 * 1.00 * 0.09 ) 
 = 4.36 
Dmax3 = project max fillet weld = 12.00
Dmax=min(Dmax1, Dmax2, Dmax3) = min(3.94, 4.36, 12.00)
 = 3.94 

Dihedral Angle, DA = 67.90 deg.
Gap on Obtuse Angle Side if No Bevel = 0.14 in.
Use weld size
Acute Side  D1 = 4.00
Obtuse Side D2 = 7.00 (weld size increased on obtuse side for gap at skew per AWS D1.1/D1.1M (2015, p.511, C-5.21.1))

Weld Strength :

Vertical weld capacity during shear only load, phi * Rnv1 = 0.75 * 1.86 * 14.50 * (3.94 + 3.94) = 159.05 kips

159.05 kips >= Reaction V = 20.00 kips (OK)

Check Effective Throat:
Acute Side Effect throat  = (D1/sin(DA)) * cos(DA/2) = (0.25/ sin( 67.90)) * cos( 33.95) = 0.22 in.
Obtuse Side Effect throat = (D2/sin(DA)-tshpl/tan(DA))*sin(DA/2) = (0.44 / sin(67.90) - 0.38 / tan(67.90)) * sin(67.90 / 2) = 0.18 in.
Total Effective Throat    = 0.22 + 0.18 = 0.40 in.
Total Effective Throat of Square Case = 5/8tp * 2^0.5 = 0.23 * 2^0.5 = 0.33 in.
0.40 >= 0.33 (OK)
