Building isolation rubber bearings are widely used and technologically mature isolation devices. By placing seismic isolation devices at the base or a certain location of the building, a seismic isolation layer is formed to separate the upper structure from the lower foundation, thereby isolating or dissipating seismic energy, avoiding or reducing the transmission of seismic energy to the upper st
The application of rubber isolation technology is safer, more reliable, and more economical than traditional seismic technology. The main characteristic of traditional seismic technology is "resistance", where the foundation and ground of a building are firmly connected together. Due to the occurrence of earthquake vibrations, the upper structure moves, and when it exceeds the bearing capacity of the material, it will cause significant damage to the decoration and internal equipment of the building; Seismic isolation technology separates the upper structure from the lower foundation through the isolation layer. The stiffness of the isolation layer is small, which can effectively reduce seismic response by 70% -90%, equivalent to reducing seismic intensity by 1-2 degrees, and saving engineering costs by 5% -20%. It is widely used in lifeline engineering, key construction projects, and ordinary building construction. In addition to new construction projects, it is also widely used in the improvement and reinforcement of old buildings, and is considered a major leap in seismic technology.
