Engineering News Formula - Timber Pile
Engineering News Formula - Timber Pile
(OP)
An old dwg prepared by USACE references the following:
'Min. length of round timber piles 30-ft; or driven to a firm bearing so as to support a load of 25 Tons, calculated by the Engineering News Formula.'
My question is whether or not the pile load referenced is allowable or ultimate. My understanding is that the ENR calculates allowable capacity (with a usual factor of safety of about 6), so I have assumed that the load referenced is an allowable load. Is my assumption correct? Any thoughts?

Some which calculate Qu and some which calculate a 'safe load'
which I assume is Qu.
What does the original formula calculate?

Nice Pun, Buggar, but you only exceeded the safe working stress because the stress was buggered up due to upward groundwater seepage pressure - something that doesn't seem to come into play in LFRD . . .
