Bearing capacity formulas listed in a paper

[icupat11]

Howdy, does anyone know of a good paper/thesis (or program) that has a list of bearing capacity calculations and their applicability (eg. for sand, or for clay or combination, etc).

Terzaghi, Meyerhoff, Hansen and Vesic are the classics. I'm sure there many variations on these.
Each one may require slightly different input information - understood.

I understand there's based on shear theory and settlement theory. I'm interested in both.

I'm imagining someone has a thesis out there that lists them, but havent' found it.
Maybe there's a excel file or program for purchase that has them?
I'm imagining a list of a 30-50 anyways - that let's you quickly compare their assumptions and decide which is most applicable for your subgrade.

thanks a ton

Shallow Foundations: Bearing Capacity and Settlement, by Braja M. Das

thanks.
that does have a few more of them then listed by me above.
to close this from my own end with a few more resources.

found Das you mentioned here, look at page49 to 51, mention of Hu (1962) and Balla (1964) are ones I hadn't hear before - there's a good comparison graph:

Following article there's a good comparison graph and includes Eurocode7 method:

Meyerhoff, Vesic, Hansen, Terzaghi seem to be king for shear method.
Meyerhoff for foundations near slopes.

icupat11, that's good info, I did not know about that book from Das. From the title (Bearing Capacity and Settlement) it looks interesting...

Back in 2012 or so the ASCE Geo journal had a number of papers, various months, on improving bearing factors. Check them out. But, I am not a big fan of wasting much time on bearing capacity. Spend your time looking at settlement/deformation - that rules almost always

 

[icupat11]

BigH - Do you have a recommendation for a comparison paper on settlement/deformation?
Timoshenko or Schmertmann come to mind.

Structural engineers still like allowable bearing capacity.. and often don't have a great idea of allowable settlement. I know, likely getting the bottom of what the allowable settlement is likely is very important to providing an accurate and relevant geotech answer... but bear with me on this adventure....

For your reference, my 5th edition of Bowles's book has a comparison table for immediate settlements using several methods. It is Table 5-3.

Also, on your comment about the bearing capacity concept from structural engineers, I was talking with an architect/structural engineer some time ago and he mentioned that his allowable settlement is zero !!. I said, so put everything on piles to bedrock, but even that you may not be getting zero settlements. It was kind of frustrating conversation. He did not understand how settlements are computed, but at the end he agreed with the geotechnical recommendations about allowable settlements...
