The focus of recent research in structural control has shifted from active systems to semi-active devices for mitigating structural response. Semi-active control devices do not introduce mechanical energy into the controlled structural system; rather they manipulate system properties in an optimal manner to reduce the structural response [1]. A semi-active system originates primarily from a passive control system with an option to modify its physical properties according to a prescribed control law. Semi-active control systems were first studied for civil engineering structures by Hrovat et al. [2] In other fields, such as automotive vibration control, considerable research has been done on semi-active systems [3,4]. A number of devices are currently being studied in the area of structural control, namely variable-stiffness devices, controllable fluid dampers, friction control devices, fluid * Corresponding author.
