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.
第一看点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让朋友圈清清爽爽
a,max = 1.89in.a,max = 2*t+.625
a,use = 1.15in.Use a,eff in design
