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.

Abstract: A resilient wave reducing structure which reduces waves propagating on liquid surface from propagating over the reducing structure and a method of constructing the wave reducing structure. The wave reducing structure of the present invention may be used to form a calm water surface region for harbors, for areas where construction work is being done or for areas where marine sports are to be performed etc. The resilient wave reducing structure includes at least one energy absorbing device having a resilient body constructed on a bottom of the liquid bounding the region where waves have to be reduced and filled with surrounding ambient liquid. This reduces the amplitude of waves passing over it by consuming the wave energy while it deforms according to the pressure distribution change caused by the waves and by radiating its kinetic energy into the liquid and the ground surrounding it.
