| Abstract |
Recently, the development of new structural system is doing actively in the field of building construction and concrete filled steel tube structure is spotlighting in this viewpoint. Under these backgrounds, nowadays many studies is being done about concrete filled steel tube column structure, but study direction is converged in study in steel materials viewpoint and study in concrete viewpoint is insufficient.
Accordingly, this study investigated to properties of structural behaviors for high-strength concrete filled steel tube column with key parameter, such as kinds of concrete, diameter to thickness ratio, slenderness ratio and etc. Also, we executed comparative analysis with every country standards formula (AISC-LRFD, AIJ, KSSC) that is presented in existing. As can know is standard of the various countries, capacity can say that decrescent thing with Lk/D ratio increase is characteristic. |
