Corner eccentric pad

Corner eccentric pad

Corner eccentric pad

Hi there

Is there anyone knows how to calculate the moment and bearing capacity of a corner eccentric pad, the pad is sitting at the corner which taking load from two walls above. one wall in left hand side sitting on the edge of the pad, and the other one is forming an angle of 70 to the other wall, and sitting on the other edge of the pad. The pad is forming a special shape due to this. I'm struggle to figure this out. Anyone knows what formula or what standard I should use?



RE: Corner eccentric pad

You've got a few options:

1) Don't have a pad. Use the walls to distribute the load out to your strip footings.

2) Place a triangular footing in the corner that spans between the walls and is reinforced to reflect that.

3) Strap beam. This the most direct and, unfortunately, most expensive alternative.

4) Use the weight of the footing and overburden to mitigate the eccentricity. This doesn't work worth a damn for serious loads.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: Corner eccentric pad

You could also create a moment connection between the in-situ wall and the pad/strip footings to reduce the rotation of the footing and use the whole (or almost) surface of the footings to take the bearing.

This approach will require more reinforcement in the external face of the wall due to moment transferring into the footing.
