ABSTRACT

The importance of viaduct as vital structure from structure of terrestrial means of
communication imposes a reduction in their exposure to shocks and disasters from
natural (earthquakes) and human (heavy road traffic) causes. In order to diminish or
even abolish effects of vibration from heavy road traffic or seismic activities, innovative
modular systems for shock and vibration insulation must be introduced in their
structure, capable to disperse the energy accumulated in the system. In order to define
these systems as accurately as possible from the functional parameters perspective, a
unitary analysis methodology for dynamic characteristics and behavior means will be
created, following the intense and varied dynamic demands coming from road traffic
and seismic activities.
