Historic Steel Shapes
Historic Steel Shapes
(OP)
Greetings,
A co-worker and I are preparing plans for an addition to an existing building and have come across a call out for a steel beam that does not appear in our available references.
It is called out as an "8 I 18.4" and I was hoping someone out there could help us out with the section properties.
Thanks in Advance
Rik

If you need the detailed physical measurements, let me know they are listed also.
Please note that there is a "modern" section S8x18.4 that is listed in the ASIC Manual, Ninth Edition but it's properties are slightly different that the historic one you have requested.
RE: Historic Steel Shapes
Thank You. The info you supplied is just what we needed.
We don't have an AISC Manual that predates the 8th. We did see the new S shape but weren't sure if the old I was just renamed. Sounds like it wasn't.
Looks like we'll be buying the steel shapes data base from AISC.
Thanks again.
