We need to examine exposed column-base resisting mechanism subjected to bi-axial bending, understand exposed column-base resistance characteristics. Moreover, resistance mechanism of exposed column-base varied working stress. Therefore, A study of exposed column-base generally behavior was necessary for moment resist frame with braced member on three dimension reaction of ground motion. Its problem understand are very difficult.
In this paper, the target structure was 1-bay-1-span solid of moment resist frame with brace and exposed column-base, its discussed three dimension resisting behavior subjected to simple loading pattern.
