Interference of shallow multiple strip footings on sand

Abstract EN

In the present study, the effects of multiple strip footing configurations on the bearing capacity and load-settlement curves of sandy soil were investigated using nonlinear finite element analysis.

Two and three strip footings resting on sand were analyzed.

In each case, different footing distances were applied for the purposes of comparison among all of the results.

From these results, it was observed that the load responses of multiple strip footings are similar to those of the single strip footing at distances greater than four times the footing width.

Also, a design equation necessary for quantifying the values of the bearing capacity ratio for the different multiple strip footing configurations were derived.

Experimental test results from the literature were selected to verify the used nonlinear finite element method.
