Construction Materials Seismic Isolator for Buildings.Multi-Rubber Bearing is the example of Bridgestone's cutting-edge technology with practical safety applications.(1) High reliability.Proven track record Since 1984,Bridgestone MRBs have pioneered the way in seismic isolating rubber bearings.No damage during recent large earthquake:Effects of thermal aging of laminated rubber bearing on 1.Introduction.The laminated rubber bearing is a type of seismic isolation bearing that a reinforcing steel plate is laminated between rubbers in form of layer so that it prevents the buckling behavior of rubber for vertical load and maintains high vertical stiffness while showing the flexibility of rubber in the horizontal direction.Elastomeric Bearing with Steel Plate - Bridge BearingLaminated elastomeric bearing pad,one type of reinforced elastomeric bearings,is made of multi-layer rubber and reinforced with steel plate through sulfuration and adhesion.Compared with non-reinforced elastomeric bearing,it has sufficient vertical rigidity which can reliably transfer the concentrated down-loads and impact loads of the superstructure to both ends of the pier.
The natural rubber (NR),used in most of the rubber bearings,has the disadvantage of poor ozone durability.This implies that the performance of the rubber bearings is easy to deteriorate due to aging.Recently,some instances of rubber bearing damage caused by aging deterioration requiring repair works have been found.Granor Elastomeric BearingsGranor&manufactures in accordance with Australian Standard AS.5100.4 from natural rubber.Granor&has successfully responded to virtually every type of elastomeric bearing challenge.The result is a comprehensive catalogue of Elastomeric Bearings covering:Hercules Engineering - Hercules Slipjoints and Herculon HLMB bearings consist of a stainless steel top plate roughened on the upper surface and polished on the lower.This plate slides against a Hercuflon coated natural rubber pad that is bordered by polystyrene strips.Types.There are two basic types of HLMB bearing available Standard,and Seismic
