Project 3.08: Bridge Modal Identification via Video Processing and Quantification of Uncertainties
Bridge Modal Identification via Video Processing and Quantification of Uncertainties Project 3.8 Project Summary Bridges form a critical category of the U.S. transportation infrastructure, yet the current structural condition is only evaluated at “C+” according to the 2017 ASCE Infrastructure Report Card. In addition to the fact that 9.1% of the bridges in U.S. are […]
