#104 SJ joist & #126 SJ-1950s 1

I ordered the 80 year historical joist book but it will take a few days to get it. Would anyone be kind enough to share the allowable load tables for these joists in the meantime!

Thanks,

Some more search on google helped me find these load tables. Here is the link:

I have the book - but your "sizing" is messed up??

Can you get more specific??

Mike,

I am not sure if I understand your question correctly but the joists on the existing drawings have been called out as #104 S.J. and #126 S.J.

As I noted - those don't make "sense"?? At least I can't find them in the book!!! in the 50's or 60's.

WHOA - just happened to open to a much older section - 1930's

From Jan 1, 1930 -

SJ104 was good to 100,000 in-lbs and max end reaction 0f 2200 lbs. Looks like max span was limited to 20' - not sure why.

SJ124 - 115,000 in-lbs and max R of 2300 lbs. Span limit was 24'

Found 1948 & revised 1952 - same as above

Hope that helps
