Time-frequency analysis of sensor data for detection of structural damage in instrumented structures

摘要: 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 Matlab that provides assistance assessing condition system with excellent visualization tools interaction user. Data were obtained from an actual bridge, strain gauges which located Nova Scotia, Canada. Experimental results are close agreement analytical calculations natural frequencies damping ratios provide remotely, useful information on possibility damage.
