RE: Structural column strength chart
bruhn (probably niu too) has a complete section on column allowables, and how to generate them (it's not that hard)
RE: Structural column strength chart
why would the welded section be twice as effective as non-welded ? ... heat-affected zone increasing the allowable ?, but wouldn't this benefit be localised to the weldment ?
i'll assume you know the euler equation.
the johnson curve, for short columns, is a parabola with a max. strength of fcy, and tangent to euler at 1/2*fcy

There are "C" factors (end fixity) missing from the .GIF file you have.
