<p>EACS 2016 Paper No. 146<br></p><p>This paper investigates the application of multiple
passive absorbers incorporating inerter(s), spring(s) and damper(s) to suppress
vibrations in a multi-story structure. Different
from the one terminal mass element, the inerter was proposed as a two-terminal
element, with the property that the applied force is proportional to the
relative acceleration across its terminals. The device can be configured to
include gearing, hence allowing a far higher inertence than device mass. The
advantage of using a TID as a suppression device mounted at the bottom of a
multi-storey building has been identified. In this paper, a five-storey
building model with two TIDs subjected to the base excitation is studied. Both
of the these devices are located at the bottom. The criterion selected for the
optimisation is the minimisation of the maximum relative displacement of the
building. Furthermore, the resulting structural responses are compared to the
case where a single TID is used at the bottom, to show the potential benefits
that arise from using multiple devices. In addition, we show that the resulting
optimal inertance needed for each device is smaller compared to the case where
a single TID is used between the ground and the first floor, which makes the
suppression system easier to manufacture.</p>
