I am preparing for a site inspection where I hope to identify an open web steel bar joist (Alberta, CAN).
I just want to make sure that I collect enough information, on the joists in particular, so that I can identify/verify them, or find them in an old catalog, or reverse engineer if necessary, the capacity for a proposed set of rolling library shelves.
In short, can I expect to find a manufacturer's name or other identification on the joists or should I plan to measure everything with a tape and caliper?
Just for context, the construction drawings show the system as:
125mm (5 inch) slab
150mm x150 mm (6x6) - p35/p35 WWR
38mm (1.5in) x 0.762mm (22ga) steel deck
406mm (16in) deep OWSJ @ 1000mm (~40in) o.c.
spanning 6000mm (~19'8")
The loading was specified as
LL = 3.83 kN/m (263 plf) (~80psf)
TL = 7.42 kN/m (510 plf) (~155psf)
Thanks in advance.
