Soils Under High- and Low-Cycle Loading - Experiments vs. Predictions by Constitutive Models
The behaviour of soils and foundation structures under a cyclic loading with either a high or a low number of cycles is discussed. Regarding the high-cycle loading, the validation of a high-cycle accumulation (HCA) model is demonstrated based on successful recalculations of element tests, model tests on monopile foundations with different scales and a full-scale test on a gravity base foundation for offshore wind turbines. The well-documented settlements of a ship lock over about two decades could be reproduced with the HCA model as well. Regarding the low-cycle loading, two databases with numerous undrained cyclic triaxial tests performed on either a coarse-grained or a fine-grained soil are introduced. The data for sand is used to inspect three constitutive models with a focus to low-cycle loading.
