| Outline of Final Research Achievements |
The H-shape column that is subjected to the compressive axial force with the bending moment was testing in this study. Additionally, a numerical simulation that is using finite element method was also conducted. The structural performance of the H-shape column was compared with the design rules that are stipulated in the recommendation published from AIJ. From the comparison study, it can be recognized that the current design rules provided conservative results on strength and ductility; the actual structural performance of the H-shape column is not used in the design. Finally, the design rules to evaluate the strength of the column was shown; the formulae that can evaluate the strength and ductility were proposed from the regression analysis of the test and numerical results.
