Design rotation angle: 0.06rad max
Design displacement: Normal shear strain value: 1.0
Usage Temperature: 25℃-60℃
LRB is made from laminated rubber bearing with a central lead plug and has great energy absorption capability. The laminated bearing is designed to carry the weight of the structure and provide post-yield elasticity. The lead core deforms plastically under shear deformations.
