| Outline of Final Research Achievements |
Strength deterioration behavior of a CFT column subjected to the lateral load with constant displacement were discussed by the experimental study and literature survey. Strength of CFT column made of the high strength steel H-SA700 whose effective length - depth ratio is 16 did not decrease after 100 cycle loading, even though the displacement amplitude rotation angle was 2%.
By the analytical study, the ultimate strength, the lateral stiffness and the stress condition of CFT columns were examined. The analytical parameters with which CFT columns exerts the full plastic moment were shown. Ranges of the analytical parameters with which CFT columns yield when the allowable strength was reached were shown.
