NO.3: The realize of the sliding HDR bearing dispalcement is through the sliding friction of the ptfe plate and the corrosion resistant plate that on the top of the HDR bearing.Low friction coefficient made the HDR bearing load low friction.By sliding friction sliding to realize the functions of vibration isolation. No.2:The HDR bearing is instaled on the bridge pier and bearn with sleeves and anchoring rod.The embedded steel plates are installed on the top of bearing but the bottom of the bearing have no embedded steel plates installed.The sleeves are fixed on the bottom seal layer steel plate by assembling bolt.The top embedded steel plate is installed on the top seal layer steel plate by shearing force cogged.The top embedded steel plates are designed to be welded installing with sleeves. NO.1:The HDR bearing is installed on bridge pier and beam with sleeves and anchoring ord,the embedded steel plates are installed on the top and bottom of bearing ,the sleeves are fixed on the top steel plate and bottom steel plate of the bearing by assembling bolt,the top and bottom embedded steel plates are designed to be welded installing with sleeves. In this paper, experimental test of a multi-level SMA/lead rubber bearing isolator(ML-SLRB) was conducted and mechanical responses of the isolator were. Variations covered include S1 0.6g, Site Class D, unequal pier heights, 45 0 skew, Spherical Friction Bearing (SFB) and Eradiquake (EQS) isolators. While the multi-level SMA/lead rubber bearing isolation system (ML-SLRB) has been proposed and numerically studied, its application remains a challenge in the absence of experimental validation. Therefore, studying their stability is crucial to ensuring the stability of the bridge system itself. High damping rubber bearing HDR is made of a rubber compound with high natural rubber (NR) content and has been specially designed to combine friction damping and viscous damping.As a result, it offers excellent functionality as a seismic isolation bearing, providing restorative attributes of rubber springs along with superior damping performance and high-level durability. Isolator: Lead-Rubber Bearings (LRB) These five attributes are varied (one at a time) to give 12 additional examples as shown in Table 1. Elastomeric bearings (EB) and lead-rubber bearings (LRB) are used in bridge structures to reduce vehicle vibrations, wind loads, and earthquakes. Performance of lead-core rubber bearings (LCRBs) is. Size Range:Lead Rubber Bearing from 400mm *400mm to 1750mm*1750mm with capacities of up to 4,000 tons are manufactured.Custom dimensions are available for special applications.ΔΆ.High Damping Rubber Bearing For Bridge and Building In this study, a brief literature review focusing on elastomeric isolators is given.
