Concrete foundation treated like a base plate and eccentricity question
Concrete foundation treated like a base plate and eccentricity question
(OP)
Hello,
I am currently designing a concrete foundation that fits into an area of 6m wide x 7m deep x 1.2m thick. It will be holding a large belt winder that will create lots of shear and torque on the foundation. The moment and shear are so large that i need to anchor the foundation into the rock below it. Now that I am trying to find the bearing on the foundation I figured I could treat it like a base plate. Is this an ok assumption? Also my moment is so large that M/P = e is larger than the size of the foundation (i.e. e>N). I cant find anywhere that says this isnt ok but my instinct tell me it shouldnt be OK.
a basic sketch is attached that might help out
Thanks,
ah

Being underground, count a way or other with any potential corrossion that may affect the anchoring system.
The contraption being a foundation for dynamics loads requires either a conservative and simple approach (that might require even more massive foundations) or a FEM structural model and analysis that cares for the relevant factors of its dynamics.
