Vibration reduction of a structure using viscoelastic dampers installed by cables

Abstract eng:
In this study new installation scheme for passive dampers was proposed using cables installed in such a way that relative displacement equal to story displacement occurs between the cable and the structure when the structure is subjected to lateral load. The cables can be installed continuously or discretely between base and top story of the structure. To verify the validity of the proposed method nonlinear dynamic analysis of model structures with viscoelastic dampers installed using the proposed configuration scheme was carried out using three earthquake records and two sinusoidal forces. According to the analysis results the proposed method resulted in significant reduction in the size of dampers compared with the conventional installation methods.
