Steve and Doug,
Thanks for looking those up and for your offers. I have found the sections mentioned in design guide 15 with the properties. I'll be making a field trip next month and I'll be measuring flanges and webs etc... to determine which of these is the best choice or if I need to calc section properties myself.
No need to send all the properties at this time, I was just hoping that someone had a list of H sections that were 18" deep... sounds like a nomenclature issue with the original design drawings.
Gerard,1945 AISC manual lists WF 18x8-3/4 weighing 70 lbs/ft, and American Standard beams 18x6 at 70 plf.Email me privately if this is what you need.V. Steve Gordin, SE

From the AISC Design Guide 15 and other resources, I can't find any information on H shapes deeper than 16". Also, the lighted 16H is 170 plf... so I have a case here where the H shape is deeper than anything I have info on and much lighter than the nearest tabulated shape of similar attributes.
If anyone out there has a resource that may have info on this shape and could kindly forward that info to me, I'd appreciate it.
Also, if you think perhaps another shape would have been used and H is just something that distinguished columns from beams (aka standard practice), your opinion would also be appreciated. I see there are several non H shapes that would match the depth and weight per foot.
