Development of cyclic loading models for application in offshore geotechnics

点击翻译按钮获取中文摘要

The response of foundations for offshore structures to repetitive (cyclic) loads is a critical but still inadequately understood area of offshore geotechnics, with designs still usually based on simple modifications to monotonic loading conditions. In this project, a definitive framework for modelling cyclic behaviour will be established. Using this new approach, numerical models will be developed to address problems at all scales from fundamental constitutive behaviour of soils to macroscopic models for large foundation systems. Their application to offshore design problems (for renewable energy as well as traditional oil and gas applications) will be assessed. Recommendations to current international guidelines will also be made.
