Influence of Counterforts in Ret Walls
Influence of Counterforts in Ret Walls
(OP)
In a cantilevered concrete retaining wall what are some standard practices that any of you take for including the influence of either a 90 degree bend in the wall or a counterfort. I have typically used a 1 to 1 ratio but think that may be unconservative. I was wondering what other engineers do. Thanks

An FEA analysis is most helpful to see bending forces in wall elements and, if the footings are also modeled with springs (compression-only springs, spring constant = Modulus of Subgrade Reaction), to see soil pressure distributions. Stability for overturning is probably easier by free-body hand calculations.
Does anyone else have experience with retaining wall FEA modeling?

Moments and Reactions for Rectangular Plates, U.S., Bureau of Reclamation, Monogram 27, W.T. Moody. Should be able to find it on the web, formed the basis of,
PCA, Rectangular Concrete Tanks. Try also;
Bowles, Foundation Analysis and Design,, 12-14 Design of Counterfort Retaining Walls.
Don't find much Finite Difference work, but thats the analysis method utilised in the first two references.

I have Monogram 27, let me know how you make out. I'm only mildly in the computer age though.
