Abstract

In the present study, the effects of multiple strip footing configurations on the bearingcapacity and load-settlement curves of sandy soil were investigated using nonlinear finiteelement analysis. Two and three strip footings resting on sand were analyzed. In eachcase, different footing distances were applied for the purposes of comparison among allof the results. From these results, it was observed that the load responses of multiple stripfootings are similar to those of the single strip footing at distances greater than four timesthe footing width. Also, a design equation necessary for quantifying the values of thebearing capacity ratio for the different multiple strip footing configurations were derived.Experimental test results from the literature were selected to verify the used nonlinearfinite element method.
