Yield Strength & Steel Design
(OP)
I am a little rusty on steel design. I have some old plans which state the building was designed using ASTM A36. I've been using LFRD but realized that the manual uses 50ksi for wide flange only. What resources are there for checking moment resistence for A36 of this shape?

Better still, write yourself a spreadsheet.

The spec is set up for any yield strength means that you can use the formulas in the spec to calc the allowable bending strength based on any yield strength. That does not mean that you can use a 50 ksi table for a 36 ksi beam!!
Is there an engineer in your office you can talk to about this?

I do not think you are rusty, rather you never were polished on steel deisgn the way you are approaching. Better have someone review your work.You cannot use this equation Mp=Fy*Z unless section is compact and laterally braced etc.

If not continuous Lp is border line (7.49'). I will do the math to be sure (F1.2) and being compact, based on B5.1.
