摘要：Skirted foundations are considered a viable foundation type for a variety of offshore applications,facilities for the oil gas industry and structures where scour is major concern. These foundations are gradually replacingpiled foundations which leads to cost savings through reduction in materials and in time required for installation. Inoffshore structures, power transmitting cables and earth retaining structures, the lateral forces acting on the footingsmay be dominant. Thus there is need to study performance of skirted footings subjected to lateral loads. In the presentstudy, lateral loading tests were performed to shed some lights on the performance of rectangular skirted footings.Different parameters studied were effect of embedment depth of skirt to footing width (D/B) ratio, number of skirtsprovided to footing and different load inclinations and their effects on the ultimate horizontal loads attained by footingwas investigated. From the results of laboratory tests, it was found that increase in the number of skirts and D/B ratioincreased the ultimate lateral load carrying capacity of footings significantly. Locations of skirts with respect to loadingdirection also have significant effect on the ultimate lateral load carrying capacity of shallow footings. Load carryingcapacity of footing increases with increase in inclination of load in plan.
