RE: Hay storage

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Farm Building Design by Loren W. Neubauer and Harry B. Walker, 1961 edition contains the following information:


Loose hay weighs 4 pcf, chopped hay weighs 12 pcf and baled hay weighs 15 pcf.  The load table indicates that the weight of loose and chopped hay varies with depth; but does not provide any additional guidance.

Thanks for all the slab buckling responses.  Now I have two much easier questions regarding barn loading;  1) Is a barn considered an agriculture building if the owner wants a two car garage as part of the main level?  2) What storage loading should be used for the hay lofts? (what's the density of hay anyway?)  Thanks again.
