Abstract: An anti-earthquake bearing apparatus for bearing the weight of a structure and reducing the vibration energy propagating to the structure by using bearing bodies disposed between the structure and a foundation or another structure has spherical bag-like bearing bodies serving as said bearing bodies formed by sealing a fluid, rubber-like solid or gas into bags constituted by a rubber-sheet material reinforced with fiber. Each bag-like bearing body is provided with charging/discharging ports. Recesses for preventing positional shift of said bag-like bearing bodies are formed on the bottom surface of the structure and on the upper surface of the foundation.

Abstract: An anti-seismic rubber is made by laminating a plurality of rigid plates and flexible plates having viscoelastic properties alternatively. At least one of the flexible plates A has elasticity, i.e. magnitude of the stress corresponding to an arbitrary strain in a stress-strain curve, lower than the elasticity of other flexible plates B in a low strain zone, and in a high strain zone, elasticity of the flexible plate A is higher than the elasticity of the flexible plate B.
