Design Parameters:

Lug Yield Strength, Fy = 52ksi

Lug Ult. Strength, Fu = 71ksi

Edge Dist., a = 1.537in.

Edge Dist., e = 1.537in.

Lug Width, b = 4.845in.

Rounded Edge? = No

Will Pin Rotate Under Load? = No

Hole Diameter, dh = 1.772in.

Pin Diameter, dpin = 1.378in.

Lug Thickness, t = 0.630in.

AISC Factor of Safety, F.S.1 = 5.0

AISC Factor of Safety, F.S.2 = 3.7 F.S.2 = max{3, Fy/(Fu/F.S.1)}ASME Notation

ASME Factor of Safety, F.S.3 = 3.0 Assuming Category B lifters

AISC Preferred Geometry AISC Alternate Geometry

Results:

Check Geometry:

Check 1: O.K.dh - dpin > 0, Pin fits in hole, O.K.

Check 2: O.K. a >= max(0.5*dh,2*t), Plate Proportions are O.K.

Check 3: O.K. e >= 0.67*dh, Plate Proportions are O.K.

Check 4: N.G. e < 1.33*a, Use a,eff = min(a, 3*e/4, 4*t, dh*1.25) in design

a,eff = 1.15in.3*e/4 controls

a,max = 1.89in.a,max = 2*t+.625

a,use = https://www.wendangku.net/doc/a512303535.html,e a,eff in design
