Abstract

Blue Road Research and the University of California at San Diego have been collaborating over the past four years to develop a system employing fiber Bragg grating strain sensors and modal analysis to provide real-time, quantitative information on a bridge’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. In the latter part of 2004, this system will be installed on the Broadway Bridge in downtown Portland, Oregon, USA. In preparation for this deployment, the system is undergoing testing from the sensors through the readout unit and bridge modeling to ensure its performance once installed. The steps of preparation and testing are discussed here.
