Study on inelastic buckling and residual strength of H-section steel column member

摘要

The inelastic buckling behavior and residual strength of H-section steel column member under axial compression loading is evaluated in this study considering different parameters. The parameters that were examined are the slenderness ratio, end constraint condition, buckling strength of the column members; the post buckling compressive resistance including strain hardening effect and axial deformation. Non linear finite element analysis was carried out for each of these parameters in this study on H-section column members. The FE analysis conducted was verified through compression loading test by comparing the inelastic deformation shape and buckling load-axial deformation relationship and satisfactory results were found.
