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.
In use, natural rubber has proved superior to all other rubbers as bridge bearing material. The design and positioning of the bridge bearing allows the vertical loads (deck and traffic) to be taken by the rubber in compression and horizontal deflections (expansion and construction) by the rubber in shear. High vertical stiffness is achieved by the insertion of horizontal metal plates, which do not alter the required low Elastomeric Bearings - DOSHIN RUBBER ENGINEERING - Natural rubber bearings possess distinct advantages over alternative metal roller types, being easier to install, free from corrosion and requiring no maintenance, factors important in the economics of bridge building. In use, natural rubber has proved superior to all other rubbers as bridge bearing material.
Since the 1995 Kobe Earthquake, rubber bearings (elastomeric bearings) have been extensively used in the construction of new bridges or in the rehabilitation of existing bridges as the replacement of conventional steel bearings to apply the horizontal seismic force distribution design and the seismic isolation design concept to achieve improved seismic performance. G 9.1 - Steel Bridge Bearing Design and Detailing Steel Bridge Bearing Design and Detailing Guidelines Section 1 Elastomeric Bearings 1.1 General Commentary This section is intended to assist in the design and detailing of elastomeric bridge bearings.

SEISMIC ISOLATION BEARING FOR BRIDGE AND BRIDGE A seismic isolation bearing interposed between a bridge pier and a bridge girder in a bridge is adapted to support the bridge girder with respect to the bridge pier, and is adapted to attenuate through the plastic deformation of the lead plug the shear deformation in the bridge axis direction of the other end in a laminated direction of the laminated body with respect to one end in the laminated direction of the
Numerous studies have proved the efficiency of rubber bearings in reducing the seismic-induced forces of bridge systems [9, 10]. The common types of rubber isolation bearings include low damping natural rubber bearings (LDRs) , natural rubber bearings (NRBs) [3, 6], lead rubber bearings (LRBs) , and high damping rubber bearings (HDRBs) [2, 8].Multilayer Natural Or Neoprene Rubber Bearings - Buy Multilayer Natural or Neoprene Rubber Bearings are made of multilayer Neoprene/EPDM/natural rubber with or without sheet steel after inlay, conglutinate, vulcanization.
