Equivalent Quasi-Static FEM Procedure for Estimating Settlement from Tipping or Dumping Impact
1. Introduction Tipping, dumping, or accidental dropping of heavy masses can generate short-duration impact loads that produce local settlement and permanent ground deformation. Such effects may be critical where the impact occurs close to foundations, retaining walls, buried services, pavements, or other structures sensitive to ground movement. A fully dynamic analysis of these events would…
Eurocode 7 Design Approaches: Hidden Pitfalls and Practical Recommendations
In Eurocode 7, the partial factors used for STR/GEO limit state verification are grouped into sets for actions or effects of actions (A), soil or material parameters (M), and resistances (R). The selected combination depends on the relevant Design Approach and may also be further specified in the National Annex. Design Approach 2 (DA2) uses…
Capacity of steel core piles – a pseudo elastic approach
Steel core piles are often regarded as the “Rolls-Royce” of foundation systems: they are highly capable, but also expensive, and their production and transportation come with a considerable carbon footprint. That alone makes optimal design not merely desirable, but necessary. Yet current practice is often far from optimal. In many cases, steel core piles are…
