<p>EACS 2016 Paper No. 124</p><p>This
interdisciplinary research work of civil and electrical engineers deals with
the piezoelectricceramic material, lead zirconate titanate (PZT) and its
potential future use as a semi-active structural control device in a civil
engineering context. The study examines first what is currently known about
piezo ceramics and their existing applications in fields such as energy
harvesting and as sensors. The main part of the paperdeals with implementing
piezoelectricceramics as a semi-active damping system for the vibration control
of lightweight non-structural components. This procedure is experimentally
analysed forthe damping response of an oscillating aluminium cantilever beam.
The study shows that, by using an RLCequivalentcircuit in conjunction with a
piezoelectricceramic transducer, the vibrations in the beam due toan initial
disturbance issignificantly reduced. By correctly optimizing the components
within the circuit, the resonance frequency of the circuit can be tuned to the
natural frequency of the beam. The experiments show that an optimal choice of
circuit parameters may increase the damping performanceup to180%.</p>
