STRUCTURAL CONTROLIn order to control a structure, a thorough identification of the structure should bedone. The identification should be done not only in the normal condition but itmust be done during the external severe events (strong winds or earthquakes).Sensors placed in structures are useful not only for structural control but also forstructural identification.In what fallows, the problem of damage identification is seen to be solved.However, even for such situation, the problem remains very complex. The author'sexperience is showing that an increased number of sensors and active devices is theonly solution for large active controlled structures; see Figure 5 for a model used inanalysis [11]. The next methodology is not the only possible one. However, it isshowing what happens when many active devices are placed into structures. Thismethodology does not limit the size of the structure or the number of devices.
