Glenn: I see that you've got a bunch of different answers to your question. I'll just add a little more: >From Bethlehem Structural Shapes, dated 1926 (book owned by my father) Section no. B9 Depth: 9 wt/ft 20.5 plf Area 6.02 in2 web t .25 in flange width 5.50 in Ix 85.5 in4 Sx 19.0 in3 Iy 8.53 in4 Sy 3.10 in3 I notice that the maximum stresses shown is for 18 and 16 ksi, used for "Quiescent Loads", and 12 ksi used for moving loads. It's probably a good idea to physically measure the beam the best that you can and then take your pick of the information that's been offered. Neil Moore, S.E.

Does anyone have any historical information on the section properties and material properties? The building is at the Norfolk Naval Base in Virginia. I believe this pre-dates AISC and maybe ASTM. I guess steel was already in production, so it isn't iron. Thanks. > >Also, I would like to nominate myself for one of the top 100 structural engineers of the century. Really. Hey, I mean it. Quit laughing. I think I'm pretty good. > >Glenn Otto, P.E. >LIBERTY ENGINEERING, P.C.
