Summary

This report presents the experimental characterization tests for two natural rubber antivibration bearings, conducted on January 18th 2008 and February 19th 2008 by the CRGP (Centre de recherche en genie parasismique et en dynamique des structures) at the Université de Sherbrooke (Canada, QC).

These tests were carried out for Produits HEVEA Inc., bearings supplier, and took place in the structures laboratory of the Civil Engineering Department.

The main purpose of these tests was to determine the static and dynamic compression stiffnesses of the bearings, following a predefined testing procedure.

The report first describes the experimental setup for the static and dynamic tests, including the instrumentation. The experimental characterization procedure and the analysis calculations are then presented.

Finally, all experimental results (tests curves and calculated values) conclude the report.
