Retaining Wall Design Programs

[OneHotYoda]

Are there any programs online that will design a reinforced concrete cantilever retaining wall with a shear key in the footing?

Due to geometric constraints, I cannot use piles and the retaining wall have no heel.

I did a preliminary design using PENNDOT's retaining wall design program (ABLRFD), but it gave me a footing 14.25' wide by 3.67' thick for a retaining wall that is only 11.5' high! (The allowable bearing pressure is only 2000 psf).

I'd like to reduce the width and thickness of the footing by implementing a shear key, but the ABLRFD program does not permit the use of a shear key in it's design.

Thanks!

Google them - might have what you want

Why not calculate it by hand. It's easy enough.

Wrote my own for my HP41C and my old Apple 2+ (basic), 30 years ago, with the shear key option, surcharge option, P load to top of wall option, to name a few.

Things have changed...
