Standardisation Of Earthquake Isolators:
A Case Study

Abstract
Base isolation of buildings has proven over the last years through international
research and implementation activities to be mostly promising for earthquake
safety. Nevertheless for the practicing engineer all presently available isolator
devices are restricted to relatively difficult application procedures due to a lack
of supporting frame conditions from the respective national earthquake codes.
For enabling an industrialisation, standardisation and economic effectiveness, as
regards different isolation needs, seismic sites and vertical loading conditions
resulting from the building construction typology, as well as a non special skill
demanding construction in conventional low-rise residential buildings, an
innovative series of adaptable isolators with a highly flexible set up has been
developed. Following the construction development of the isolator the elastic and
hysteretic behaviour of prototypes under different vertical loading have been
investigated in 1:1 scale in dynamic laboratory tests. Their mechanical properties
have been determined and the respective linear-equivalent SDOF systems have
been analysed in the time-history range for ten characteristic earthquake
components of the Greek Mediterranean region.
Keywords: structural control, base isolation, dynamic loading tests, hysteretic
behaviour, seismic performance.
