Post Embedment Equation

[LowLax]

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?

You got it. I brought it up in this thread some time ago.

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

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.

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.
