Abstract
Structural control through base isolation and energy dissipation systems has been
increasingly implemented internationally in recent years and has proven to be
one of the most promising strategies for the earthquake safety of structures.
Nevertheless, only recently there have been applications of passive structural
control in Cyprus. Whereas the integration of passive damping devices within a
structure aims at the energy dissipation within specific structural zones, the
concept of base isolation aims at the minimization of the input seismic energy
above the isolation level. This paper gives an overview of the current application
status of the control techniques to some civil structures in Cyprus: a multi-storey
r/c building of the Cyprus Sport Organization with steel diagonals and viscous
dampers; a cable suspended footbridge with tuned mass dampers; three
commercial buildings of steel bare rigid frames and braced frames, where base
isolators in the form of high damping rubber bearings, elastomeric bearings and
friction pendulum bearings are placed on top of the basement columns; a retrofit
planned for a multi-storey building for the Telecommunications Authority of
Cyprus, partly to be supported on friction seismic isolation devices; and four
highway bridges, supported on either elastomeric bearings with dual lead cores
or on friction pendulum bearings.
Keywords: structural control, seismic isolation, energy dissipation, seismic
performance.
