[AT] OT - Load calculation for barn loft

[charlie hill]

Mike you might be able to find it online.  I don't think the allowable live 
floor load is more than about 20 lbs per sf.  on a minimum standard floor. 
I may be way off on that.  Sistering another 2 x 8 would certainly help.  A 
2x10 would be better if you have room.   However, with all that said, I've 
seen some pretty rickety old barns with 80 lb bales of hay stacked 8' high 
from corner to corner up stairs.

Thanks Charlie, it looks a little skimpy to me, seeing as how they designed 
the loft to have hay in it. I figured if the 2x8's were too light for the 
job, I could sister in another one to make it more sturdy. I have about 350 
bales of hay up there now, which is a pretty good load, but we are looking 
to add another 100 bales to that.

Mike I can't do the load calculations for you but if my memory is correct a
floor system with 2 x 8's on 16" centers 13'6" long is the MINIMUM allowable
floor load for an FHA home. I'm not sure what the allowable live load is.
Maybe someone has the charts or formula.

Hi All, just wondering if there are any engineer types on the list that
could give me a rough idea on the type of weight I can put in our barn hay
loft. The side we store hay on has 2x8 framing on 16" centers with a 12 foot
span. Load is carried to the ground with (7) 6x6 posts on each side. I just
want to make sure we don't overload it. Thanks for any help that can be
given.
