A Review of Dynamic Response of Adjacent Structures Connected by Friction Damper (Coulomb Friction Model)

The conventional structural systems are highly unlikely to provide adequate performance in the event of a major earthquake. To improve seismic resistance of buildings, various control techniques are adopted. One such control technique is passive control device. Passive control device are used in many buildings to mitigate the seismic effects. This passive control device is essentially used between two adjacent structures in big cities. Desire for safer and increased demand for the seismic control of buildings is the main reason for adopting passive control devices. One of the types of passive control device is friction damper which is used to dissipate the energy and provides a protection system for seismic structures. Friction dampers utilize the mechanism of friction force for absorbing and dissipating the energy imparted to the dynamic systems. It has now become economically feasible to design high performance structures with the emergence of friction dampers. This paper includes the use of friction dampers in structures for mitigating the seismic hazards to structural and non-structural components of building.
