INTEGRATED HEALTH MONITORING AND VIBRATION CONTROL OF BUILDING STRUCTURES: METHODOLOGY
In most of the current investigations, health monitoring and vibration control have been treated separately according to the primary objective pursued even though the two systems both need sensors, data acquisition and transmission for real implementation. This separate approach is not practical and costeffective if structures do require both health monitoring and vibration control system. This paper thus presents an integrated procedure for health monitoring and vibration control of a building structure using semi-active friction dampers. The concept of integrated system using semi-active friction dampers is firstly introduced. A model updating scheme by using semi-active friction dampers is then presented to update the stiffness and mass matrices of the building and to identify its structural parameters. The control strategies of semi-active friction dampers using local and global feedback control are proposed. A damage detection scheme based on adding known stiffness using semi- active friction dampers is finally proposed and used for damage detection. The feasibility and accuracy of the proposed integrated procedure are demonstrated in the accompanying paper through detailed numerical examples and parametric studies.
