This document specifies the test methods for determining the mechanical characteristics of large size elastomeric seismic protection isolators subjected to dynamic velocity loading representative of seismic actions. The isolators covered by this document consist of multilayered vulcanized rubber sheets and reinforcing steel plates, as defined in ISO 22762 1.
The test methods include the application of horizontal dynamic loading, with or without simultaneous vertical loading, in order to evaluate:
— shear properties under dynamic velocities;
— vertical load bearing performance under dynamic conditions;
— large deformation behaviour;
— ultimate shear properties, including breaking, buckling, and roll out displacement.
These methods are intended for test pieces of dimensions representative of isolators used in actual structures (hereafter “large size isolators”). The tests are applicable to isolators used in buildings, bridges and other structures requiring evaluation under seismic level dynamic loading.
This document is intended to be used in conjunction with ISO 22762 1, which specifies general test methods for elastomeric isolators, and with ISO 22762 2, ISO 22762 3, or ISO 22762 which specify design related requirements for isolators used in bridges and buildings, respectively.
This document does not specify the design requirements of isolators, nor the criteria for their acceptance in specific structural applications. These matters are specified in ISO 22762 2, ISO 22762 3, and ISO 22762-6.
