In this study, emphasis is placed on ductility enhancement of thin steel box-section columns. The effects of lateral stiffeners are tested with hydraulic actuators with computer control. From the experiment, it is observed that the reduction of aspect ratio by dense lateral stiffeners works effectively to limit the local buckling in the stiffenered area where the maximum flexural moment occurs.Due to the limitted local buckling, the deterioration of restoring force after the ultimate point becomes less and larger energy absorbing capacity can be expected. Hybrid earthquake loading tests also verify the effectiveness of the dense lateral diaphragms for ductility enhancement of thin steel box-section columns. キーワード(英): - 記事区分 - 区分    委員会論文集
