Özet
T he engineering systems are the potential damage ac- cumulated structures at environmental and operational conditions.The most research conducted in structural health monitoring (SHM) has focused on ways of detecting the damages in these structures at the earlier possible time.The ability of monitoring accurately the all parts of the structure is crucial to improve both the reliability and safety.During the last two decades, the structural monitoring techniques have been focused to diagnose the damage by equipping the structure with various types of sensor.One such a monitoring procedure is vibration based damage identification which is based upon the changes in dynamic response such as crack, stiffness reduction or loosed connection that alter the response of that structure [1][2][3][4].There has been a much research on this field such as Doebling et al. presented a review for the vibration based damage detection techniques [5].The model based SHM approach is generally implemented by building a physics based model for the system.Once the model of the system is established based on a physical description, it is updated
