Demand for monitoring systems applied to structures for quality assurance and for evaluating seismic risk is stronger than ever. Here, a monitoring systems to assess structural integrity was developed in which the damage-detection strategy uses two methods to first identify the damage sites globally (i.e., detect whether the damage occurred or not, and detect the story level) and to then evaluate the damage sites locally. It is shown that the local damage identification used the wave propagation method to analyze a concrete bar. Results showed that these two methods are practical and effecive in assessing structural integrity of a structure for seismic safety.
