Stress Calculations:
Allowable Stresses:
Pole: fa = axial / Area =
53.0 psi Fa = Fcy/ny = 17,727 psi
fb = OT Mom / Sect Mod. = 19241.5 psi Fb = 1.17-Fty/1.65 = 17,727 psi
fv = (2'shear/a)+(torsion/1)
= 424.3 psi or Fb = 1.24'Ftull.95 = 19,077 psi
CSR's:
use use 17,727 psi
Post: CSR = fa/Fa + (fb/Fb)+(fv/Fv)^2
= 0.82 Fv = Fsy/ny = 13,473 psi
csr < 1.0 so OK!
Check Embedment Depth of Pole:
REF: FBC Table 1819.6 &1819.7.2.1
d=•0.5A(1 +(1 +(4.36h/A))^1 /2)
Where:
A = 2.34P/(S1 b), where S1 = 2'S'd/3, S = 150.00 psf
d= Depth of Embedment in feet 8.00 ft
b = Diam of Post, Concr or compacted fill 0.50 ft
S1 = Soil Pressure = 800 psf
