point of fixity for a concret pier foundation
(OP)
how can i calculate the point of fixity for a concrte pier foundation used to support a new house. the pier will need to be embedded at least 5 feet into formational materials with an overall min embedemnt of 10 feet, vertical bearing capacity is 10,000 psf, up to 30,000 psf. 24-inch diamter.





RE: point of fixity for a concret pier foundation
The point of fixity is the point at which the earth pressures adequately resist a couple created by the moment or resist the lateral shear, or both. I would go beyond that a bit just because of the variability of soils.
Your bearing capacities seem a bit high. What kind of material are you in?
I'm also a bit confused by your question/statement. Are you trying to determine the capacity of the pier? Is your lateral load high?
