Study on polyurethane elastomer modification for improving low-temperature resistance of high-capacity polyurethane elastomeric bearing for bridges

Seismic Performance and Suitability of Elastomeric and POT PTFE Bearings for Girder Bridges

“…Xiaoxing Xu et al 9) studied the application of isolation bearings in cold regions. Kazeminezhad et al 10) investigated that depending on the degree of rotation lateral displacement limit, the isolator's vertical stiffness could be altered Since elastomers have a high strainrecovery capacity, they are ideally suited for use as base isolators.…”
