QUAKE-ABSORBING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a quake-absorbing structure capable of absorbing vibrations acting on the structure with a simple structure.SOLUTION: The quake-absorbing structure includes: a base isolation column 10 which is disposed between a first member 8a and a second member 8b in an inclinable manner and which has an end surface 9a, at both ends of the base isolation column 10 respectively, which comes into contact with the first member 8a and the second member 8b; and a tilt fulcrum forming member 15 that is disposed enclosing the end of the base isolation column 10 and which serves as a supporting point when the base isolation column 10 begins to incline. The quake-absorbing structure further includes an eccentric member 11 that forms an inner edge portion 14a which is closer to the base isolation column 10 on the end surface 9a and an outer edge portion 14b which is positioned at the opposite side of the inner edge portion 14a being interposed by the base isolation column 10 and which is positioned farther than the inner edge portion 14a from the base isolation column 10 at both ends of the base isolation column 10.
