1950's steel joist 2

I've got 14J5 from the 1970 steel manual, but not 14SJ5 so I don't know if it they are the same.

Allowable loadings given for this designation are common from the SJI load table effective January 1, 1930 thru the last load table effective before your date of 1950 which was revised to June 1, 1948. Steel designations varied slightly over these years so you might want to take the 321 plf for the 18' span with a grain of salt (I provided a load for the 19' span which was common to all the load tables). The properties shown for this joist were

14" depth
156,000 inch pounds allowable moment
2900 pounds allowable end reaction

14' - chart is blank
16' - chart is blank
18' - chart is blank however, 321 plf is indicated for the load table adopted by SJI in September 1952
19' - 288 plf
20' - 260 plf
22' - 215 plf

No DL/LL breakout was indicated, loads shown were total load
