Overview

This research examines structural skirts improving uplift resistance in shallow foundations, suggesting a viable alternative to piles.

Key Points

  • The aim is to evaluate the effectiveness of structural skirts in enhancing the uplift resistance of shallow foundations compared to piles.
  • Utilized a square footing model with a data logger and loading system.
  • Examined two groups of skirts (chamfered and straight) under various properties.
  • Conducted tests under different displacement rates (0.5 and 2 mm/min).
  • Compared performance of unmodified, skirted, and piled footings on loose sand.
  • Skirts with L/B ratio of 2 and 45° angle with wings enhanced uplift resistance 9 times more than piles.
  • The best configuration achieved a 10.25 times increase in uplift capacity.
  • Skirted footing outperformed single piles in uplift resistance.
