Abstract
This project proposes the derivation of new models and methods to study dynamic soil-structure interaction problems. We propose to develop coupled methods involving boundary-, finite- and discrete-element formulations, as well as perfectly matched layer schemes. Novel constitutive models will be incorporated to represent grains and the soil as granular media. Neural network computational efficiency schemes will be developed to enable large-scale analyses. Transient solutions will be derived for the analysis of transient phenomena such as earthquakes. These methods will enable optimization analyses of problems involving the soil and other unbounded media, including appropriate constitutive laws, the accurate consideration of the flexibility of supports and energy dissipation, and the inclusion of various objective functions, constraints and loading that are suitable to represent vibrating structures. The proposed methods will greatly increase our understanding of how structures behave, and help engineers and architects to design optimized large-scale, vibration-sensitive facilities such as particle accelerators, nuclear powerplants and grain silos, as well as to devise strategies to protect them against ground vibration. The proposal also includes a plan for a new and improved teaching curriculum, which is based on modern learning philosophies, and that promotes inclusion, while providing relevant and updated content for the student's academic and professional careers.
