Outline of Final Research Achievements

The purposes of this study are following. The first is a quantification of the deformation capacity of the steel structure frame with lateral buckling. Second is the proposal of the lateral bracing method of a beam which has sufficient deformation capacity. The third is acquisition of the experimental data of the post-buckling behavior of frame.
The numerical analysis and the small scale frame test were carried out. The deformation capacity of a beam within a frame was presented using the analysis data. Moreover, large deformation experimental data of spatial frame with lateral buckling was provided. Furthermore, The method that bracings are placed near plastic hinge and the remainder as equal distance of lb/iy≦100 was proposed.
