    Upper limit for soils' bearing capacity (ULS)

    Hi everyone, I have a geotechnical report that provided an Ultimate Limit State (ULS) bearing capacity of 2000 kPa for silty sand soils with N-values greater than 50 (reaching about 70 blows per 0.3 m). My question is: Is there an upper limit to the ULS value where a geotech would not consider...

    Settlement vs Foundation Size

    Thank everyone, and sorry for wasting your time on this. I am not really a Geotechnical engineer, but work with few and I am trying to understand how things work in the geotech world. I agree with CarlB, I believe there is a typo in this equation, but I don't access to the CFEM to confirm, as I...

    Settlement vs Foundation Size

    Hey everyone, In the CFEM, there is an equation by Burland and Burbidge (1985) for foundations on normally consolidated coarse-grained soils: \[ S = B^{0.75} \times \frac{1.6}{N_{60}^{1.4} \times q} \] I believe that this equation is based on observed data, but there are a couple of things I'm...

    ULS and SLS

    Could someone please explain how to evaluate bearing capacity using ULS? (I'm in Canada, if that makes a difference.) I have tried finding answers and reading reports, but I never clearly understand how ULS and SLS are calculated. 1) Is ULS a factored ultimate bearing capacity? If so, why do...
