Seminar - Yun Zheng - Interaction of a Coupled Model for an Offshore Pile
Wednesday 31 October 2007, 1.10 - 1.50 pm
Civil Engineering Lecture Theatre 3
A coupled model is developed to investigate the dynamic interaction between an offshore pile, the seabed and seawater. The pile and seabed are described by Biot’s dynamic theory, while the seawater is characterized by the Helmholtz equation. Three boundary element formulations are constructed for the pile, seabed and seawater and the continuity conditions are used to formulate the model for the system. The dynamic response of the system is calculated and a numerical example is used to demonstrate the capacity of the coupled model.
