|This paper reports results from 1g model tests carried out under single gravity on a skirtedfoundation installed in sand and subjected to a rapid uplifting force. The effects of displace-ment rates ranging from 5 mm/s to 450 mm/s on the ultimate capacity, suction pressure insidethe skirt compartment, and time of extraction were investigated. Test results indicate that thedisplacement rate significantly affected the magnitude of uplift resistance, as well as the magni-tude of suction under the foundation lid, but had little effect on the relationship between stressand the displacement of the foundation. The shapes of the uplift capacity-displacement curveand the suction-displacement curve were similar for all experimental displacement rates.
