Traditional structural health monitoring (SHM) techniques are often based on the assumption that the loading is either absent or can be treated as a stationary random variable. Many of the current SHM methods also necessitate strong actuation or an excessive number of sensors unsuitable for high-speed applications. Here we present an SHM technique that detects the type and extent of the damage in the presence of variable environmental conditions. The model is tested with virtual simulations, and data acquired from the structural sensors are analyzed with a time-frequency realization technique to retrieve the system information and the location and extent of potential damages. It is shown that the proposed method is robust to the environmental effects and can be used for high-speed applications.
