  • Construction having a damping device
    Patent number: 5259159
    Abstract: A construction having a damping device for damping vibration having steel wire cables 20 having both ends fixed on the sides of the building 10, the steel wire cables 20 are tautly and obliquely provided on the building 10 so that one side and the other side of the steel wire cables 20 cross at only one point in front view. Since the steel wire cables 20 do not exist in the horizontal direction, the length of the steel wire cables 20 is shorter as compared with the prior art. Accordingly, extension of the steel wire cables 20 decreases, the mechanism is simpler, and maintenance is also simplified.
