Abstract

Finite element analyses of the uplift behaviour of a typical pyramid-shaped foundation as used to support electricity transmission towers are described. Reasonable agreement is found between uplift capacities for foundations in dense cohesionless soil from the finite element computations using the OASYS package DYNA-3D, and from several simplified limit state analyses. Computed soil displacements are in broad agreement with observed failure mechanisms around model foundations. Uplift capacities from DYNA analyses are 20 percent higher than those predicted from centrifugal model tests at 53 gravities, while computed displacements are 40 percent less than observation.
