| Outline of Final Research Achievements |
The authors have been investigated Steel and Concrete composite columns (SC columns). In this thesis, the sesmic performance of SC columns of the octagonal cross section was investigated. For the difference of axial force ratio, material strngth and the steel flange width-thickness ratio to examine the effect on the elastic-plastic behavior of the SC columns, experiments and analysis were carried out.
Result of the studies, the following mentions became clear; 1)this octagonal cross sectional columns have good earthquake resistant properties. 2)Since the ratio of action axial force against the compression strength of the cross-section is as high as about 0.5 steel flange buckles, reinforced by the band plate becomes effective. 3)As a result of the elastic-plastic analysis of SC columns, this analysis revealed that it is possible to accurately track the experimental behavior.
