A Review of Parallel Structure Connected by Friction Damper using Viscoplasticity Model

Friction damper is used for the dissipation of an earthquake energy which may cause damage to the structure. It is a well-known energy dissipation devices. The purpose of this study is to analyze a single-degree-of –freedom (SDOF) building structure. Friction damper is used to connect parallel structure with each other. Friction damper is installed between two parallel structures to reduce inter-story displacements of structures subjected to the external loading. Numerical model (Viscoplasticity model) is used to model the friction forces in the proposed damper. The equation of motion is solved by the Newmark’s step by step method and seismic response of structure is worked out under earthquake excitation. Friction damper is used to reduce the structural seismic found response. The mutual pounding of structure is also reduced by structure with a friction damper. It is that during major earthquake, the friction damper slip at a predetermined connecting load before yielding occurs in member of a frame structure and dissipates a large proportion of seismic energy during earthquake. In this paper investigation is carried out to study the structural response of a parallel structure connected by a friction damper using. The specific objective of this study is to evaluate the importance of a friction damper in reducing the seismic response of parallel structures which are connected by friction damper with each other.
