| Research Abstract |
This research project succeeded in imparting an apparent mass effect of 5, 000 t to a conventional rotary viscous damper, which is referred to as the rotary damping tube (RDT), by attaching a cylindrical flywheel having an actual mass of about 1 t. Shake table tests using a real-life damper verified the mass amplifying effect. It is also elucidated that a seismic control system using this damper, the tuned viscous mass damper, can impart arbitrary damping only to the specified mode and almost never changes the mode shapes of all the modes. A simple seismic response evaluation method based on the SRSS method and a practical damping evaluation method is proposed and is applied to a structural design in practice.
