Subject: RE: Distribution Width for Concentrated Load on Concrete Wall
The code used to say, I am not sure if it still does, but for walls a concentrated load is spread over B+4T where B is the bearing width and T is the wall thickness. The recent tilt-up design methodology allows the load to be spread out further on a 2/1 spread on each side of the load.

Subject: Distribution Width for Concentrated Load on Concrete Wall
I’m designing a C.I.P. concrete cantilevered retaining wall. I’m trying to find the distribution width for a concentrated load at the top of the wall. So far, I’m unsuccessful. In masonry, it’s called a “flush wall pilaster” and there is clear direction if the wall is masonry.
Is concrete the same as masonry in this regard?
