Paper Abstract

Blue Road Research and the University of California have been collaborating over the past three years to develop a system employing fiber Bragg grating strain sensors and modal analysis to provide real-time, quantitative information on the structure's response to a dynamic input (such as a seismic event), and a fast prediction of the structure's integrity. This research, being funded by the National Science Foundation, has several publications showing its strong progress. This year marks a significant step forward in this effort, with the successful completion of a full-scale test performed on a longitudinal carbon shell girder being tested as part of the planned I-5/Gilman Advanced technology Bridge in California, USA.
