australian steel section tables circa 1900
hi,
as part of floor loading assessment for an historic building, i have noted one of the main structural i-beams to be 380mm deep approx by 150mm. unfortunately, this doesn't correlate with anything in the current steel section tables.
would anyone have steel structural sections table for the period 1870-1910? i suppose iron may have been the construction material as well then (hopefully not though) so any section tables for that era would be appreciated.
many thanks
find a job or post a job opening
quick question is it a welded i beam or a tappered flange beam as was the standard of the day?
when in doubt, just take the next small step.

it was a tapered flange section, like an rsj.
re  
if its a british beam and standard i may be able to help.... aisc has design guide 15, which is a reference for historic shapes and specifications. this guide includes information on many shapes that predated the aisc manuals.
this seems to be a free search engine for section properties:
i believe the australian steel industry only got started during wwi.  before that, most of the rolled sections came from the uk.  a lot of the old beams from that period have some kind of stamp on them, e.g. "scotland".  some of our uk friends may be able to help.
the historic structural steelwork handbook can be downloaded from here:
there's a 15x6x45 beam
