An experimental time-frequency analysis framework is developed for monitoring the occurrence and location of structural damage in instrumented structures such as bridges. We make available a software package written in Matlab that provides assistance in assessing the condition of the structural system with excellent visualization tools and interaction with the user. Data were obtained from an actual experimental bridge, instrumented with strain gauges which is located in Nova Scotia, Canada. Experimental results are in close agreement with analytical calculations of natural frequencies and damping ratios and provide remotely, useful information on the location and the possibility of damage.
