Load settlement curve method for spread footings on sand Conference Paper uri icon


  • A newly developed method is presented to predict the complete load settlement curve for square spread footings on sand loaded at their center with a vertical load and with an embedment from 0.25 B to 0.75 B where B is the footing width. This method also allows one to obtain the settlement of the footing as a function of time for a given load. The basis for this new prediction technique is a complete preboring pressuremeter curve. The method is developed after performing finite element simulations and after performing 5 full-scale footing load tests pushed to 0.15 m of vertical displacements. Footing widths vary from 1 to 3 m. The new method satisfies observations from the experimental results including the fact that there is no scale effect on the load settlement curves for these footings if those curves are plotted as pressure versus settlement over width.
