| Outline of Final Research Achievements |
The spatial structures are also used for evacuation facility and disaster prevention base in a time of disaster such as an earthquake or a typhoon. Therefore, the purposes of this study are to propose the design method for vibration control devices for spatial structures. First, the vibration control devices that have high applicability to the spatial structures are selected. As a result, TMD (Tuned Mass Damper) is elected. Next, the response reduction effects of the cylindrical lattice shell roofs which are often used for the roof of gymnasiums subjected to the horizontal or vertical earthquake motions are examined by numerical analyses. Lastly, the evaluation method for response reduction effects for spatial structures with TMDs is proposed and the validity of this method is verified.
