Abstract:The objective of this study was to investigate the seismic performance of laminated elastomeric and lead-rubber seismic isolation bearings under cold climate conditions. To this end, comparative test results are presented of laminated elastomeric and lead-rubber bearings in warm and cold temperature conditions. The effect of strain rate is also investigated. The mechanical properties of elastomers are time dependent. Strain rate has an influence on the behavior of rubber and must be accounted for when modeling the laminated elastomeric and lead-rubber base isolation bearings.
