If you like Table 4-12 in the AISC 15th Edition, then you might like the attached example plots which I built on the same principle.
AISC 15th Edition LRFD maximum axial capacities in kips; KL in feet
Maximum axial capacities are tabulated for KL/rx <= 200 and KL/ry <= 200
Fy = 50 ksi
Conventional plate thicknesses = [0.25, 0.375, 0.5, 0.625, 0.75, 0.875, 1, 1.25, 1.5, 1.75, 2]
Gusset thickness and eccentricities are similar to AISC 15th Edition Table 4-12 for single angles
Gusset plate thickness = next larger conventional thickness plate, given 1.5 X tf_detail
Example for WT4x12:
Therefore, tf_detail = 0.375”
Therefore, t_gusset_theoretical = 1.5 x tf_detail
t_gusset_theoretical = 1.5 x 0.375”
t_gusset_theoretical = 0.5625”
t_gusset_used = 0.625” (next largest conventional)
Example for WT4x12:
Therefore, eccentricity = t_gusset/2
Therefore, eccentricity is ≥ 0.75 x tf_detail
eccentricity = t_gusset/2
eccentricity = 0.625”/2
eccentricity = 0.3125”
Included self-weight in the moment (assuming members might be horizontal)
No fireproofing weight
Included amplification factor to P delta moment
