| Outline of Final Research Achievements |
Two types of new response control mechanisms are proposed. One is a system of a base isolated structure which shows rocking movement against extremely large earthquake ground motions. The other is a system composed of frames equipped with passive dampers and hardening elements with gaps. In the former system, the seismic force of the structure is suppressed by rocking motion for unexpectedly large earthquake ground motions. In the latter system, the structure shows full capacity, by changing their vibration modes corresponding to their vibration amplitudes. The effectiveness of these systems are verified by conducting response analyses of multi-degree-of-freedom models and vibration tests of small sized models and a loading test of scaled frames equipped with the proposed system.
