A skirted footing is a type of semi-deep foundation that has a vertical or inclined wall constructed on one or more sides of its periphery. Skirted footing can provide better bearing capacity as the rigid skirt confines the soil under the footing and resists vertical and lateral loads, resulting in reduced settlement of the footing. This paper shows the outcomes of a parametric analysis of field-scale unskirted and skirted square footing in loose sand using PLAXIS 3D software. The parameters such as skirt depth, footing size, and number of skirt were varied during the study. The impact of these parameters on bearing capacity was analyzed. The numerical analysis showed that the skirted footing significantly improves the bearing capacity of the foundation. The results indicate that increasing the skirt depth increases the bearing capacity. The study also revealed that the increase in the number of skirts does not always guarantee an increase in the bearing capacity of the skirted footing. The performance of singly and doubly skirted square footing depends largely on the size of the footing. The findings of this study can be used as a guideline for the design of square-shaped skirted footings in loose sandy soils.
