Corners (a,b) 43.1 in
V1=V4 = 21.6 in.
Z = 0.4
I = 1.5
Cp = 0.75
Fp = Z x I x (Cp) x Wp = 0.45 x Wp
2194 lbs.
33.00 in.
Wp (max) = 2145.0 lbs x 1.15 = 2777.25 lbs.
Wp (min) = 1785.0 lbs. x 0.85 = 1517.25 lbs.
Fp = 0.45 x 2777.25 = 1249.76 lbs.
(Fp) = 0.15 x 2777.25 = 416.58 lbs.
Mo = 33.00 x 1249.76 = 41242.08 in. lbs.
Tension = Fp x Cg / V4 = 3213.6 lbs.
Shear = Wp(max)Fp/4 lbs., each anchor= 603.8 lbs.
EXAMPLE: <Rawl Power Bolt # 6913>
3/8" embedded 2.5" / min 2000 psi concrete
Tension rating of bolt: 5200 lbs.
Shear rating of bolt: 7270 lbs.
Interaction = (T/Tbolt) + (S/Sbolt)
Interaction = 0.7
Interaction = < 1.00 (OK)
