ABSTRACT
The current research on the synthesis of structural health monitoring and vibration control was introduced in Chapter 14. The synthesis of structural health monitoring and vibration control in the frequency domain, based on variations in the frequency response functions between the two states of a building that are created by using semi-active friction dampers, was also discussed in Chapter 14 in relation to system identification, vibration control and damage detection in a systematic way. However, the integrated procedure in the frequency domain introduced in Chapter 14 is not the real-time integration of health monitoring and vibration control of building structures; it requires the semi-active friction dampers to create the two states of a building structure and the external excitations and structural responses to be measured and transformed in the frequency domain. External excitations such as earthquake-induced ground motions are difficult, if not impossible, to measure directly and accurately on site and other semi-active control devices may not be able to create the two states of a building structure. The field measurements, including the input and output measurements, are always first recorded in the time domain. The transformation of data from the time domain to the frequency domain takes time, which may cause a time delay in the structural vibration control. For these reasons, it is necessary to develop a real-time integrated system of structural health monitoring and vibration control for building structures.
