Calculating for eccentric loads on pad (mat) foundations
Calculating for eccentric loads on pad (mat) foundations
(OP)
When loads onto pads give a resultant with an eccentricity outside the kern i am only able to locate formulae that assume single axis bending to determine the base pressure distribution.
There are published charts (Teng etc) that list factors for other cases however i would like to know the basis of the formulae if they exist at all.
Perhaps a member can point me in the right direction or, better still, advise what the formulas are.

Paragraph 24.4
Figure 24.4 "Footing subjected to moments about both axes with zero pressure under part of base"
This paragraph provides an eight step trial & error procedure for solving this type of problem.

this might not be so useful but i did work out a reasonably simple formulae to use which derives Teng's 'k' value for single or double eccentricity. Trouble is I have lost it - for now at least.
Will attempt to post it when i recover the file it is in if anyone is interested.
