Centrifuge Modeling on Pile Behavior Subjected to Cyclic Lateral Loadings

Article Preview

Abstract:

Cyclic loadings would cause the failure of pile foundation which was leading to many studies in the past. In this study, 6 centrifuge models were conducted in the acceleration field of 80 g. In order to simulate the off-shore wind turbine foundation embedded in soft deposit and subjected to lateral forces such as strong wind and waves. The pile was embedded in the dry or saturated soil deposit, and the different elevation of lateral force was applied to the pile foundation. From the tests, it was found 1% of pile head displacement suggested in the design guide is conservative.
