An advanced rate‐dependent analytical model of lead rubber bearing
Earthquake Engineering and Structural DynamicsAbstractLead rubber bearings (LRBs) are a type of isolation bearing that have a combination of rubber and lead as the main components. These bearings are widely used in bridges, buildings, and other important structures due to their high load‐carrying capacity and excellent energy dissipation capability.

DESIGN AND PRODUCTION OF LEAD RUBBER BEARINGS FOR EARTHQUAKE ABSORBERS [PDF]
Engineering Heritage Journal, 2023 Lead Rubber Bearing (LRB) is a passive type of base isolation that can be used as a damper for earthquake vibrations on bridges and buildings. The components that make up the LRB are several layers of rubber laminated to steel plates to increase vertical

Influence of Temperature on the Mechanical Behavior of Lead/Rubber Bearings. [PDF]
Polymers (Basel)The mechanical behavior of lead/rubber bearings (LRBs) is strongly influenced by both ambient temperature and hysteretic heating under seismic loading; however, their coupled effects and underlying mechanisms remain insufficiently understood. This study presents a systematic investigation of the thermo-mechanical response of LRBs through combined ...

EFFECT OF USING LEAD RUBBER BEARING ON A STEEL ARCH BRIDGE
Jurnal Teknik Sipil, 2022 A study was conducted to evaluate the application of Lead Rubber Bearing (LRB) on bridge structures. The length of steel arch bridge is 80 m, width of 10 m, and height of 19.6 m. The bridge is simply supported with two bearings on each support. Structural analysis reveals that the lateral force on the bearing is more than 400 tons (835 tons in ...
