22h7 joist capacity
 
22h7 joist capacity
i have ordered the 75 year manual for steel joists but not gotten it yet and need to have the calculations completed tomorrow for an existing joist with a new load. could someone please look up the allowable load and weight for a 22h7 joist. my span is 35'-1".
thanks in advance.
from the 1971 standard load table:
total load capacity = 286 plf
live load capacity for deflection/360 = 209 plf.
approximate weight = 10.7 pounds per foot.
