Vertical compression stiffness, horizontal equivalent stiffness, equivalent damping ratio,shearing modulus, displacement, these are necessary testing performance. Depending on different project designing requests, the parameters are calculated differently, and LRB used on bridge and LRB on buildings are requested differently.

PTFE sliding bearing, which is produced based on laminated rubber bearing pad, bonding one PTFE plate on the top of it. It is used not only on bridge, but in factories, equipment, and other industry for loading and sliding purpose.

How to produce and test rubber bearing?

According to (construction seismic design code) ( EN 15129, EN 1337), “government no.3 hospital"project seismic fortification criterion is 8 degree (0.3g)
