EARTHQUAKE ISOLATING AND VIBRATION ABSORBING EQUIPMENT FOR STRUCTURES

摘要

An earthquake isolating and vibration absorbing equipment for structures is provided with a hanger secured to one of a floor including a ground and a supported member of a structure installed on the floor, a lever, one end of which is swingably mounted on the hanger, a weight member mounted on the other end of the lever, a holder secured to the other one of the floor and supported member, and arms for connecting one end of the lever to the free end portion of the holder. The structure provided with the equipment is less influenced by an earthquake or vibrations under the action of the lever on which there is mounted the weight member having a weight far lighter than that of the structure.
