DAMAGE LOCALIZATION AND MONITORING OF LOAD CHANGES IN TRUSS STRUCTURES

In recent years one can observe an increasing interest of the researchers, both from academia and industry, in the development of systems for the monitoring of health structures.. The main fields of application for these systems are rotating machinery, aircrafts and other means of group transport and civil engineering structures. Many of the latter, contain truss elements in its structure. That is why detection and possible localization of the fault in such a structures is crucial for the safety of its operation. In this paper the application of modal filtration to damage detection and localization in the truss structures is presented. The results of numerical simulation an laboratory experiment are shown.
