CHECK EMBEDMENT DEPTH OF POLE
REF.; 1.) Florida Building CodeSection 1819.7
2.)Soil report from assumptions.
Soil is a loose brown to medium grain sand
lateral pressure = 150 psf Table 1819.6
Per Section 1819.6.1, Lateral pressure may be increased
by two times the value = 300 psf
Section 1819.7.2.1, Unconstrained
d = 0.5A[1-[1+(4.36h/A)]^0.5]
Where: A = 2.34P/(S1b)
d = DEPTH 7.0 FT
b = Diameter of pole = 5" 0.41 FT
S`: = SOIL PRESSURE = 2* SP'd/3 700.0 PSF
P = ACTUAL LATERAL LOAD 159.10 LBS
h = DISTANCE FROM LOAD TO GROUND LINE = MN 8.7 FT
SOLVE FOR "A" A = 2.34P/(S1b) 1.30
d = 0.5A[1 [1+(4.36h/A)]^0.5] = 4.21 FT <
Embedme-t depth of 7'-0" meets code.
Auger a 12" :.lameter hole and set pole T embedment depth then tamp soil in 6" lifts.
Pole are flattened at the bottom for torsion resistance
