historical joist data 30h9
i've searched everywhere in our office for joist data on these specific sizes and it looks like we need to order the 75 year manual from the sji. right now we only have the 5o year manual which only has joists in the h series going up to 24h8. anyway i was wondering if anyone would be able to pass along the information (resisting moment in inch-pounds) and (maximum end reaction in pounds) for this one particular joist (30h9), until we are able to order the newest manual?
thank you ahead of time for your help.

effective from 1974 to 1986:
30h9:
resisting moment = 1,075,000 in-lbs
max. end reaction = 7500 lbs
approximate wt = 15.4 lbs/ft
thank you very much for your quick reply, it is greatly appreciated.
