Soil-structure interaction framework for plate anchors in sand under cyclic loading

This joint PhD project is based at The University of Melbourne with a minimum 12 month stay at KU Leuven

Project description

The emergence of offshore floating renewable energy devices requires economic anchoring solutions. Plate anchors could represent such a solution due to their high efficiency in resisting tensile uplift loading. While the monotonic capacity of plate anchors embedded in sands is relatively well investigated, their performance under more realistic long term offshore environmental (cyclic) loading is not well understood. In particular, there is limited numerical capability in modelling cyclic capacity of plate anchors in sand.

This joint UoM-KUL project aims to investigate the performance of plate anchors subjected to cyclic loading in sand using numerical and physical modelling. The specific objectives of this project are to:

  1. Develop a novel 2D finite element model to predict the response of soil-anchor systems under vertical cyclic loading;
  2. Generate a laboratory soil element test database for the soil model parameter calibration and performance verification purpose; and
  3. Investigate cyclic soil-plate anchor interaction by means of laboratory model anchor parametric study in sand.

The outcomes of the project will be integrated into an accessible design tool to enable better predictability of anchors cyclic capacity in engineering practice. The successful candidate will be primarily based at UoM to conduct the experimental studies and will spend a period of 12 months at KUL for the implementation of the numerical model.

The project will be complemented by the project on Soil-structure interaction framework for monopiles in sand under cyclic loading and the collaboration will ensure a successful completion of the project.
