加熱矯正された十字柱突出板の圧縮挙動 Compressive Behavior of Cruciform Column Projection Panel Corrected by Heating
Access this Article
To elucidate the reason why the compressive behavior of specimens corrected by heating differs from that of virgin specimens, elastic-plastic large deformation analysis was carried out. When considering only residual imperfection, the experimental phenomena could not be simulated. Then considering not only residual imperfection but also the rise of yield stress made by work hardening, the experimental phenomena could be simulated totally. From the analysis, it was elucidated that the reason why the buckling mode of specimens corrected by heating changed was both residual imperfection and the increase of yield stress made by work hardening.
