| Summary: | The uplift behaviour of a typical pyramid-shaped foundation as used to support electricity transmission towers is investigated using the finite element package DYNA-3D. Reasonable agreement is found between uplift capacities for foundations in dense cohesionless backfill from the finite element computations and from several simplified limit state analyses. Computed soil displacements exhibit broad agreement with observed failure mechanisms around model pyramid foundations. In comparison with behaviour in centrifugal model tests at 53 gravities, computed uplift capacities are 20% higher, and computed failure displacements 40% less than predicted by physical modelling. |
