Re: steel beam

        I think that is what they were called before they were W12x14.  The change took place about 1970 give or take a couple of years.  Sorry I don't have any documentation to prove this; just my memory.
        I don't remember using any 12B14 beams but I did use a lot of 8B10.
        I hope this helps.

Subject: steel beam

Hi Folks:
I have a roof framing plan of an older tilt up industrial building that was retrofitted for seismic repairs.  There are some steel beams labeled
" 12B14".  Are these what they were called prior to being renamed W12x14?  If not, does anyone know what their properties are?  I have some large diameter sheet metal duct that has to be hung from the roof framing and braced for lateral and barring providing new purlins, I would like to use them if they calc.
Thanks in advance for any info y'all might have on this.
