Response of skirted foundations for buoyant facilities subjected to cyclic uplift loading
Response of skirted foundations for buoyant facilities subjected to cyclic uplift loading
This paper presents results of beam centrifuge tests carried out with an instrumented shallow skirted foundation in lightly overconsolidated soft clay. The effect of one-way and two-way concentric cyclic loading on the load-displacement response during cyclic loading and on the subsequent transient and sustained uplift resistance of the foundationsoil system is considered. The results show that residual uplift displacements and a reduction in average stiffness occurred as the magnitude of the cyclic load and the number of cycles increased, but that undrained and sustained monotonic uplift capacity were enhanced by a preceding sequence of cyclic loading.

Abstract
This paper presents results of beam centrifuge tests carried out with an instrumented shallow skirted foundation in lightly overconsolidated soft clay. The effect of one-way and two-way concentric cyclic loading on the load-displacement response during cyclic loading and on the subsequent transient and sustained uplift resistance of the foundationsoil system is considered. The results show that residual uplift displacements and a reduction in average stiffness occurred as the magnitude of the cyclic load and the number of cycles increased, but that undrained and sustained monotonic uplift capacity were enhanced by a preceding sequence of cyclic loading.
