This project was funded by the National Institute for Transportation and Communities (NITC) under grant number NITC-RR-1022. The author would like to thank the students who participated in the work contained herein and spent countless hours in research rabbit holes only to emerge and take another. Samuel Lozano, Jason Millar, Alex Antonaras, Daniel Iwicki, Phil McGovern, and Gregory Collins have each contributed substantially in mind, body, and spirit.
Bridges -- Design and construction, Strcutural dynamics
The goal of this study was to develop a cost-effective, accurate, and easily deployed evaluation tool using widely available mobile technology (specifically iPods) to measure the dynamic structural response of a bridge subjected to harmonic forcing. Researchers leveraged principles of structural mechanics, dynamics, and vibrations, as well as a significant body of literature, to conceive a system that could complement existing visual inspection methods to support bridge condition evaluation and rating. The outcome of the project is the Rapidly Deployable Structural Evaluation Toolkit for Global Observation, or RDSETGO.
