Abstract

This paper proposes a novel configuration for the passive vibration control of seismically excited buildings combining the "inerter", a recently developed Two-Terminal Flywheel (TTF) device, with the classical Tuned Mass Damper (TMD). The TTF is used as an inter-storey device acting as an "apparent mass amplifier" to the TMD mass to control the fundamental mode shape of planar framed buildings base excited by stationary stochastic processes. Pertinent numerical data reported establish that the use of the TTF in the proposed TMD+TTF configuration can either replace a considerable part of the TMD vibrating mass to achieve a significantly lighter passive vibration control solution, or improve the TMD performance for a fixed TMD mass. These data consider the mean square and the peak top floor displacement of a particular three-storey building frame equipped with optimally designed classical TMD and TMD+TTF passive control solutions for seismic input compatible with the response spectrum of the European aseismic code provisions (EC8). © 2013 Taylor & Francis Group, London.
