Does anyone now the section properties for a 8B10? I am trying to verify an existing structure for new loading conditions. The design drawings show members 8B10. I was told this could be a previous label for W8x10. Is this true? I have also looked at AISC's Shapes database. I found several beams designated B10, but I'm not sure how to determine which one is an 8B10.

I have a copy of the 6th edition of the AISC Manual of Steel Construction (1963) & it lists Miscellaneous Shapes (M) & Light Beams (B). The shape you asked about is basically an early W8x10 with some differences. I have scanned the relevant pages & attached them. As you may have guessed, the pages are yellowed & taped together so the scan is about as clear as I can get it.

ACE58 - Thank You very much.

I assume the 8x4B with a linear weight of 10plf would be the 8B10 I am looking for. This also seems to be very similar to a W8x10.

Since the 8X4 B designation contained (3) different beams as a sub-category, they apparently dropped the "X4" & added the weight per ft. (10, 13 or 15) to differentiate which size was desired.

Back then, we always used the weight instead of the width because of the rolling series' having more than one weight in the nominal size range.
