Since the United States took the lead in the use of isolation rubber bearings in the Albany Building in 1966, Japan, France, New Zealand, and China have successively used vibration-isolating rubber bearings in some important buildings. Among the currently-built base-isolated buildings, more than 80% of buildings use a laminated rubber isolation bearing system to resist earthquakes. Laminated rubber bearings are not only widely used in bridge construction projects, but also have been used in the base of buildings to isolate earthquake sources, seismic protection and seismic isolation in water areas. The practice has proved that these buildings using seismic isolation rubber bearings can withstand strong earthquakes. For example, in January 1994, the Los Angeles earthquake in the United States, and in January 1995 in the Kobe Earthquake, Japan, the use of laminated rubber isolation The buildings of the seat system show excellent anti-seismic effects. Not only the building has not fallen, but the internal facilities have not been destroyed. Therefore, in recent years, laminated and isolated rubber bearings have been widely used at home and abroad.
At present, hundreds of buildings in China have used laminated rubber bearings. Many test results show that the use of seismic isolation rubber bearings in the isolation project not only can reduce the damage to the superstructure but also the building height limit and safety distance can be appropriately relaxed. Due to the thick rubber layer on the outer surface of the rubber isolation bearing, the performance of the steel plate and the adhesive rubber layer is not reduced due to the influence of the environment, and the service life can reach 95a or more. The durability and flame resistance of rubber bearings have been proven by many tests and experiments to be fully capable of meeting the building design life requirements. In addition, isolation rubber bearings are also widely used in the isolation of buildings and water structures such as roads, railways, and subways.
