Per SJI Technical Digest No. 7, 50-Year Steel Joist Digest, the 1930
spec for a SJ102 states:
Depth = 10"
at L=14'-0" uniform load capacity = 214 plf
M capacity = 63,000 "#
Ma End Reaction = 1,900#
The above is the same for the 1949 revision of the specification.

Good Morning All
I have a building built in 1936 concrete columns and beams supporting
bar joists with a 2 " concrete slab and flooring. The existing plans
show S.J.. 102 at 23 1/2" o.c. spanning 14'-0". Can anyone give me any
information on these? I have not gone to look at them but I plan too in
the near future. Based on my experience with joists (fairly limited)
these are 10" deep joists and the 2 stands for the chord sizes (am I
correct in this)?
