12930 SW 133 Court, Miami, FL 33186 Calculations for picket fence pole embedment.
305-969-2776 FAX 305-969-3544 Mr. Camilo P. Ortega's home.
h=3', B = 1', P =F/1.33 =341.5 lbs, p =200 psf. The resulting d= 3.94'
Final calculation
Where there is no restraint such as a surface pavement the formula is
d = A 1 + l + 4.36 h
2 A
Where A=2.34 P/SIB; where S1 = pd/3. _
Replacing these values SI =263.14; A= 3.04 and d:-- 5 feet.
Check pole bending stress
The allowable bending moment for a structural steel 3"x3"x3/16" pole is 0.66 x 46 ksi x 1.73-in3 = �l
kips-in. The max moment is assumed to be at '/4 the depth of embedment below grcundliiie. Moment is
then
M=P (h+d/4). Replacing, M= 17.45 Kip-in; this is less than the allowable of 52 Kip-in
