Z = 0.4
I = 1.5
Cp = 0.75
Fp = Z x I x (Cp) x Wp = 0.45 x Wp
1254 lbs.
24.375 in.
Wp(max) = 1442.1 lbs.
Wp(min) = 1065.9 lbs.
Fp = 0.45 x 1442.1 = 648.9 lbs.
Fp = 0.15 x 1442.1 = 216.3 lbs.
Mo = 30 x 648.9 = 15818.0 in. lbs.
V1 = V4 19.3 in.
Tension = Fp x Cg / V4 = 1585.3 lbs.
Shear = Wp(max)Fp/4 lbs., each anchor = 360.5 lbs.
EXAMPLE: <Rawl Power Bolt # 6913>
3/8" embedded 2.5" in minimum 2000psi concrete
Tension Rating of bolt: 5200 lbs.
Shear Rating of bolt: 7200 lbs.
Interaction = (T/Tbolt) + (S/Sbolt)
Interaction = .35
Interaction = < 1 (OK)
