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

Abstract - In the last few years, efforts were carried out to develop the concept of energy dissipation in structures to bring it into an applicable technology. The conventional structural systems are highly unlikely to provide adequate performance in the event of a major earthquake. Several devices based on different energy dissipation principles have been developed and implemented worldwide. Connecting the adjacent structures with passive energy dissipation devices has attracted the attention of many researchers due to its ability in mitigating the seismic responses. Friction damper is one of the energy dissipating devices which dissipate the energy during earthquake. Further, effectiveness of dampers in terms of the reduction of structural responses namely, displacement, velocity and acceleration is investigated using Newmark’s step by step method. A parametric study is also conducted to investigate the optimum slip force of the damper. In this study, seismic responses of two connected structures are compared with the seismic responses of a single structure.

Keywords- Adjacent structures, friction damper, seismic response, slip mode, non-slip mode.
