| Summary: | 碩士 === 國立中央大學 === 土木工程學系 === 86 === It has been proven that the double steel tubes with concrete-
filledpoesses higher ultimate strength and ductility ratio than
traditionalconcrete-filled tubes. However, for members with
longer tubes, partially-filled-concrete members would be more
favorable then the fully-filled ones. Therefore, the relation
between the height of infill concrete and ductility capacity is
a major parameter in governing the behavior of such members.
This study is focused on the cyclic behavior of members with
different concrete-height in double steel box columns . It is
shown that the strength and ductility ratio of the specimen are
more significant if local-buckling occurred in composite
section. Relationship between member performance and self-
weight,slenderness-ratio and energy-dispation is also studied .
