| Outline of Final Research Achievements |
For a large ground motion, a damage identification method and seismic safety evaluation of steel-concrete composite structures were examined. Especially, the forced vibration testing method using a portable shaker was proposed. As the experimental results of the static loading tests, the seismic damages of RC specimens and steel-concrete composite specimens were identified based on the resonance frequencies measured by the forced vibration tests. Moreover, the stiffness distribution and stiffness decrease of the RC structures and composites structures were estimated. It was indicated that the seismic safety of the composite structure could be evaluated by FE analysis.
