Simplified failure load evnelopes for shallow foundation on dense sand

Record type: Article

Prediction of the ultimate load capacity of shallow, sand supported foundations carrying vertical (Y), horizontal (H) and moment (M) loads is a fundamental offshore engineering problem. The paper demonstrates how the complete failure envelope of such a foundation, represented by a system of parabolas and rotated ellipses, can be transformed into either a 45° inclined straight line or a unit circle by referring the applied loads to an origin located below the foundation centreline. The conjugate transformation applied to the corresponding displacements generates a symmetry amongst them, for symmetrical load paths, not otherwise apparent. Extensive, model-scale, experimental data are presented that provide strong support for the simple, transformed failure-envelopes.
