This paper introduces two distinctive means for use of a 189-meter-high damped structure ensuring the safety against earthquake.

  1. Realization of L-shaped elevational structure planning

    The bottom and top of the tower have belt trusses and hat trusses respectively to restrain the bending deformation. Furthermore, large-capacity oil dampers (damping force 6,000kN) are installed in the middle part of the tower to restrain the higher-mode deformation.

  2. Realization of L-shaped planar structure planning

We devised the means of matching the centers of gravity and rigidity by adjusting planar rigidity. Moreover, viscous damping devices are located at the edges of the L-shaped plan, where torsional deformation tends to be amplified. We call this system “Damping Tail” system.
