Steel Joist Loading

Steel Joist Loading

Steel Joist Loading

(OP)
Do the load tables in the SJI handbook already have a safety factor built in.  I am trying to determin the loading of a roof and have 22H6 joist at 6ft spacing.  I I use the live load (228plf) for this joist at 30ft. span this gives me 38psf.  Would this be the loading or should I add safety to the 38psf? Thanx

RE: Steel Joist Loading

Yes, check the SJI specifications where they provide the design criteria for steel joists.  The safety factors are similar to that used by ASD for steel shapes.
