ABSTRACT
This chapter provides a brief review of research on the synthesis of structural health monitoring and vibration control. It introduces the concept of an integrated system using semi-active friction dampers. The chapter presents an integrated procedure for the health monitoring and vibration control of building structures using semi-active friction dampers in the frequency domain. By using updated system matrices, it investigates the control performance of semi-active friction dampers using local feedback control with a Kalman filter for a building subjected to earthquake excitation. Substantial efforts have been made in the development of smart structures that synthesise both vibration control and health monitoring. In the frequency domain, the whole or partial time histories of structural responses are generally required for the extraction of modal properties for the purpose of system identification and damage detection. The health monitoring system and vibration control system are tightly interconnected and interact to make the whole system self diagnose and self-adapt in an effective manner.
