This paper introduces two distinctive means for use of a 189-meter-high damped structure ensuring the safety against earthquake. 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. Realization of L-shaped planar structure planningWe 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. |
