Development of Rapid Assessment Tools for Structural Parts after Extreme Events Using Stress Wave Methods

Recent extreme events such as earthquakes and hurricanes have shown the need for improved rapid structural assessment tools. It has been recognized that successful recovery missions greatly rely on the reliability and safety of the existing transportation infrastructure. In particular, bridges represent crucial parts of an infrastructure network and authorities need to know whether they can rely on the bridges that survived an extreme event in order to plan their recovery missions. This research will develop tools for rapid inspection of critical structural parts after extreme events using stress wave methods. Tests on small steel parts in conjunction with numerical stress wave simulation will be used to establish quantitative analysis tools that can objectively detect flaws. The developed tools will increase the resilience of the infrastructure after an extreme event and enable a faster recovery.
