✦ Synopsis

As steel columns under unexpected accidental loading exhibit a tendency of plastic deformation in large buckling, the issue has been much discussed along with the evaluation of plastic deformation capacity and restoring force of column members in the large deformation range following post-buckling. This study describes how to prevent the progressive collapse of structures using the plastic deformation energy of members and absorbing the collapse loading energy of structures. The post-buckling strength of the H-shaped steel column member and the plastic deformation capacity were reviewed by comparison with the value obtained from the loading test and the results of a non-linear FEM analysis.
