Abstract

Vibration absorbers consisting of a comparatively small mass-spring-dashpot system in resonance with the structure on which they are installed have been proven effective to reduce wind-induced vibrations in high-rise buildings, floor vibrations induced by occupant activity, and the seismic response of buildings. From the practical point of view, these vibration absorbers, first suggested by Frahm in 1909 and often called tuned mass dampers, represent an attractive alternative to protect structures against the detrimental effect of earthquakes. First of all, they require a relatively large mass and, hence, a large space for their installation. Melkumyan (2014), introduced the isolation techniques using laminated rubber bearing. Providing flexibility to the damper using laminated rubber bearings (LRBs) converts the system of an ordinary TMD into the system of an additional isolated upper floor – (AIUF), which actually is a roof isolation system.
