Eccentric Footing 2

[sponcyv]

I am dropping a column down 1/2" from the face of a wall for a renovation project. There is an existing strip footing under the masonry wall that I am pouring my isolated column's eccentric footing atop. Basically, the bottom of the bulk of the footing will be level with the bottom of the existing strip footing, but there will be a portion of the footing that is to be poured atop the strip footing. This portion will have a styrofoam strip to keep the new footing from loading the strip footing. Does anyone have a design example for this exact condition? I have attached a link to a pdf image.

Irrespective of the fee, the Engineer of Record must come up with a solution which either satisfies the problem at hand, offers a possible solution or states that a solution is not available. It is incumbent on all engineers, when faced with such situations to openly declare their limitations because, if they do not, they will be hammered in court.

dhengr,

The original drawings are not available. I like your idea about the channels. We do this on new openings in masonry walls pretty regularly. However, the layout of the concrete pilasters does not work well with this option. The room is a 37' clear spanning room. The roof dead is 30 psf and live is 20 psf (reducible). The loading on the column is 15.76 kips at 18' column spacings. Thanks for pointing out that I drew the angle seat upside down.

BA,

Thanks for your input - I have given a viable solution to the fix, didn't I?
