ANALYZING COMPOUND FOOTINGS USING THE TRANSVERSE MOMENTS

[keenkeem]

I was just wondering how does one considers the pressure of a compound footing subjected by a transverse moment?
Does one treats compound footing like an isolated footing? Does one considers the sum of axial loads and resultant moments,
(sum of axial forces)/(sums of transverse moment) determines its eccentricity, determines whether is it on the kern or not, determines whether to use P/A +- MC/I or the other formula? I haven't seen any engineers consider transverse moments and am curious as to why engineers does not consider that. I haven't seen any examples that considers it either? WHY??? Its been buggling me for a while.

I want to learn about finite analysis and its application to how it is applied to footings. Any books you would like to recommend? Free softwares that I could download? Books I could read?

Thank You

I would recommend the ACI publication: 336.2R-88, “Suggested Analysis and Design Procedures for Combined Footing and Mats".

It's a little bit dated,and talks more about mat foundations than combined footings. However, it is still a good place to start.
