The damage criteria of steel frame structure for fiber level, member level and story level are proposed. The fiber level damage criteria is directly defined by the developed steel damage model, the damage criteria of steel member is averaged through all the fibers of the member, and the story level, the damage criteria is defined as the weighted average value of the members, which the weighting factor is defined as the first several relative frequencies increase of residual structure after the evaluated member was demolished. As a numerical example, the damage process of a 9-story benchmark steel frame is analyzed through IDA (Incremental Dynamic Analysis) method in term of structural global damage index, and the damage distribution of each story is proposed as well.
