Dimensions used for calculating beam properties

Dimensions used for calculating beam properties

Dimensions used for calculating beam properties

(OP)
I understand that the beam properties tabulated in the AISC manuals are based on the smallest fillets normally available, while the dimensional information shows the largest fillets.  Is there any available listing of what the fillet sizes used for calculating properties actually are?

And similarly, the channels have a radius at the toe of the flange- is the radius dimension used for calculating properties available anywhere?

And lastly, the tables show the "average thickness" of a channel flange.  How exactly is that defined?

RE: Dimensions used for calculating beam properties

Have you tried to find an ASTM spec that has minimum tolerances for steel sections?

RE: Dimensions used for calculating beam properties

(OP)
I've got ASTM A36 and ASTM A6.  As best I recall, they don't specify a tolerance for these radii, though.
