Energy dissipation & cyclic soil behaviour
Is energy dissipation the key to predict cyclic soil behaviour?
Stavroula Kontoe, David M G Taborda, Julia Moller
High-speed railways, construction of deep foundations, offshore wind generators and infrastructure in earthquake-prone regions, all share cyclic loading patterns which are rapidly changing direction and amplitude. These cyclic loads are then transferred to the supporting soil. Therefore, the safe and economic design of a wide range of structures is crucially reliant on our ability to simulate soil behaviour under repeated, cyclic loading. Current methodologies are mostly empirical, problem-specific and offer inadequate accuracy. We aim to develop a novel, unified computational approach to address this problem based on the unique links, identified experimentally, between dissipated energy and soil behaviour.
