Assessment of the efficiency of variable friction damper for seismic protection of building
Abstract
The implementation of variable friction dampers (VFD) for vibration mitigation of seismic structures generally requires an efficient semi-active control method. In this paper, a semi-active model control method is proposed to determine the controllable clamping force of a variable friction damper. A comparative study was performed on a multiple DOF structure controlled by passive friction dampers, variable friction dampers in subsection numerical examples. Finally, this paper also provides preliminary conclusions of the advantages and disadvantages for friction dissipators.
