old structural shape properties
hello,
i am seeking information on three beam sizes.
rsj 18 x 7 1/2 x 75#
rsj 20 x 7 1/2 x 89#
rsj 24 x 7 1/2 x 95#
they come from a set of drawing of an offshore platform designed in england around 1959. if you have information on these could you please site the source?
thanks,

hi, eurobeam.
i am more than a little delighted to be able to help. but first some ancient history.
during the first year of my engineering degree course in 1952, our structures lecturer handed out a little booklet(about a5, 10 pages or so, with three pages of useful formulae, the remainder section properties of a range of sections from which all course problems would be drawn), telling us that the three pages of formulae contained all that we would ever need for our subsequent careers. by and large, he wasn't so far wrong; although it has now lost its covers, is torn and severely dog-eared, it remains in my briefcase and acts as a great reminder to re
austim,
thank you very much!
