Hi Fred,
I am the founder of Open Source Ecology (OSE) - see my TED Talk - http://www.ted.com/talks/marcin_jakubowski.
I would like to inquire if you can review our simple foundation design for a small Compressed Earth Block structure - for structural integrity.
My calculations are here- https://docs.google.com/a/opensourceecology.org/presentation/d/1ZfrvXvAP8u8e7hrkF55pZuakQkJRRPKJPb4K3w-2HmA/edit#slide=id.g3761a0abd_31
We are doing a one story home, with a 1' wide wall and 1' thick footer. I have gone through a deflection calculation for concrete, and concluded that a 6"x12" foundation with 5 sticks of 1/2" rebar would give us L/800 deflection and a safety factor of 10 for tensile strength.
I would like to get your feedback if this makes sense. If you cannot provide this service, then I would like to ask you if you could suggest another engineering consultant to verify the calculation for OSE.
I would like to explore whether this design could be verified as code-compliant in Missouri, zone 5. It is intended for use with a shallow insulated footer -
Thanks, Marcin
