Skirted Footing for Enhancing Load Carrying Capacity
Finite element limit analysis was used to investigate the performance of an axially loaded strip footing with structural skirts resting on sandy soils in this work. Three separate cases were investigated to determine the influence of skirts on the performance of skirted footing: (1) effect of skirt length and angle of internal friction, (2) effect of vertical load on lateral capacity, and (3) effect of skirts on footing settlement. The bearing capacity ratio was used to show how skirt addition improved the bearing capacity of surface foundations. Analysis of the numerical and experimental study results revealed that the inclusion of skirts improves the bearing capacity and settlement behaviour of surface foundations on sand. The improvement in magnitude increases with increasing skirt depth. Laboratory studies on small-scale foundation models were also conducted to investigate the behaviour of skirted foundations subjected to vertical loads.
