Title: Impact Forces from Tsunami-Driven Debris (NEES-2010-0942)

Year Of Curation: 2013

Description: The objective of this research project is to improve our understanding of, and predictive capabilities for, tsunami-driven debris impact forces on structures. Of special interest are shipping containers, which are virtually everywhere and which will float even when fully loaded. The forces from such debris hitting structures, for example evacuation shelters and critical port facilities such as fuel storage tanks, are currently not known. We will carry out experiments at NEES@OSU and NEES@Lehigh to improve our understanding of low speed impact of heavy debris and to develop and validate two numerical models: a simplified model that can be used for design, and a more complex fluid-structure interaction model based on computational fluid dynamics. This simulation-based model will allow us to explore complex parameters not included in the simple model and to consider scenarios not covered by experiments.
