scope:

Concerned primarily with the stability of "as-delivered,'' rolled, structural steel shapes of the I or WF type, this discussion considers the inflnence of residual stresses on the load carrying capacity of compressed members. Both the purci axial load case and that of combined thrust and bending due to end moments, eccentric or lateral loads, etc. have been included. While the procedures presented could be extended to include as a basic material property the influence of a curved type of of stress-strain relationship (in addition to the apparent nonlinearity due to residiial stresses) the numerical work involved in obtaining equations or graphs similar to those shown herein would be much greater.
