The protection of civil structures, including their material contents and
human occupants, is without doubt a world-wide priority of most serious current
research. Such protection may range from reliable operation and comfort, on one
hand, to serviceability on the other. Examples of such structures which leap to
one’s mind include buildings, towers, and bridges. In like manner, events which
cause the need for such protective measures are environmental like earthquakes
and winds, or moving loads like cars and pedestrians in the case of bridges. The
earthquake hazard is translated in severe vibrations for the structural systems. In
order to handle this world wide problem auxiliary damping devices is added to
absorb those vibrations. One of the early used damping devices is the Tuned Mass
Damper (TMD) which is a passive system in that it absorbs the structural response
without adding an external control signal. In this work a case study of three stories
building model excited by a simulated earthquake hazard is investigated versus the
response of the same building supplied by a TMD.
