Post Embedment Equation

Post Embedment Equation

Post Embedment Equation

(OP)
IBC 1805.7.2.2 Equations 18-2 and 18-3 (also "A" for Eq. 18-1)

Is the "b" suppose to be in the denominator or the numerator?

Seems like denominator would make more sense.  Increasing the pole diameter decreases the embedment depth, right?

RE: Post Embedment Equation

Right or wrong, it's been written this way ad infinitum.

RE: Post Embedment Equation

Au contraire, the 1994 UBC has it written in a less ambiguous way, with a horizontal division line, with b in the denominator, where it belongs.

Thanks for the help.  I searched the old threads but didn't find that one.

RE: Post Embedment Equation

The "Pole Building Design" document by Donald Patterson provides a derivation and a chart of the non-constrained equation.  "A" clearly ends up in the denominator.   

The document has been referenced several times in these forums. Do a search to find the link.
