seaint(--nospam--at)seaint.org,Internet writes: What criteria should be followed in deciding if the settlement of a footing is structural failure? That is, how much settlement can occur before it should be considered a structural failure? Failure is defined by two primary factors, serviceability and strength. It can fail in either one of these modes. The obvious failure is when the material ruptures or yields. That is a material failure. If settlement prevents functions of the building, even though the footing material has not ruptured, it has failed. What good would a building be if it settled so bad you could not open or close the doors or windows? Different amounts of settlement can be tolerated for different structures without causing material failure or serviceability failure, so there is no set amount. A superflat floor fails with a small amount of settlement. A pre-engineered metal building with metal siding and roofing may be able to take a significant amount of settlement and still function satisfactorily. __________________________________________________ Richard Lewis, P.E.
