抄録
A series of experiments and numerical simulations were carried out to identify factors dominating mechanical behavior of box columns corrected by heating/pressing. Local buckling deformation was generated in the virgin columns by compressive loads and it was corrected by heating below the A₁ transformation temperature and pressing. After the correction, compressive loads were applied to the corrected columns again. Although the ultimate strengths of both the virgin and corrected columns were almost the same, the buckling mode of the corrected columns differed from that of the virgin columns. When considering the geometric residual imperfection resulting from incomplete correction by heating/pressing and the increase of yield stress due to large plastic deformation caused by local buckling and its correction process, the phenomena observed in the experiment could be simulated by elastic plastic large deformation analysis. Therefore, it was identified that the factors dominating the mechanical behavior of box columns corrected by heating/pressing were the residual imperfection and the increase of yield stress.

A series of experiments and numerical simulations were carried out to identify factors dominating mechanical behavior of box columns corrected by heating/pressing. Local buckling deformation was generated in the virgin columns by compressive loads and it was corrected by heating below the A₁ transformation temperature and pressing. After the correction, compressive loads were applied to the corrected columns again. Although the ultimate strengths of both the virgin and corrected columns were almost the same, the buckling mode of the corrected columns differed from that of the virgin columns. When considering the geometric residual imperfection resulting from incomplete correction by heating/pressing and the increase of yield stress due to large plastic deformation caused by local buckling and its correction process, the phenomena observed in the experiment could be simulated by elastic plastic large deformation analysis. Therefore, it was identified that the factors dominating the mechanical behavior of box columns corrected by heating/pressing were the residual imperfection and the increase of yield stress.
