## Abstract In this paper a predictive control method especially suitable for the control of semiβactive friction dampers is proposed. By keeping the adjustable slip force of a semiβactive friction damper slightly lower than the critical friction force, the method allows the damper to remain in its

A semi-active tuned mass damper (TMD) which is capable of adjusting initial displacement and damping is applied to seismic protection of structures. Control algorithms are derived in closed forms using perturbation analysis on modal properties of the sinigle degree of freedom (SDOF) structure/TMD sy
Considerable effort has been devoted to develop passive and active methods for reducing structural response under seismic excitations. Passive control approaches have already found application in practice. Active control methods, on the other hand, are being vigorously examined for application to ci
Passive supplemental damping in a seismically isolated structure provides the necessary energy dissipation to limit the isolation system displacement. However, damper forces can become quite large as the passive damping level is increased, resulting in the requirement to transfer large forces at the
A study has been made of the use of three semi-active friction devices, herein referred to as dampers, to control the seismic response of a building modelled as three masses. With a pseudo-random earthquake input, peak lateral accelerations, inter-storey drift and base displacement relative to groun
A semi-active device for the vibration control of machinery foundations or for ride control of vehicles is proposed. A semi-active damper utilising dry friction is employed, with balance logic, a class of sequential damping, being used to minimise the force transmitted. The friction force applied to
