Large Bookcase Support


Want to add 10' x 10' bookcase in room. Wall that bookcase would sit on is parallel to floor joists. Floor joists are 2x10 crossing 16' span. Access beneath floor is difficult as it would require messing with ducts, pipes, etc. Worried that joists are not strong enough to support bookcase's added weight. Could send beam across span above bookcase and hang it from that. Would be a lot of work and would prefer someone to tell me that floor should support bookcase.

Large Bookcase Support


In most cases, the floor SHOULD handle it just fine. The edges are supported by rim joists or sill plates and should hold that weight easily enough. I'd add some screw-in support along the back of the case to the wall studs for tip stability/security as well.

100 cu. ft @ 35#/cu. ft. max gives 3500#, but rows of books probably are less dense than this, on average.

"According to the founder of online bookseller Alibris.com, an
average-sized book weighs 12 ounces. " and 500 sheets [a 2" stack] of 8-1/2 x 11 copy paper weighs 5# [46#/cu.ft.].

The deeper the bookcase, the more the weight will be transferred to adjacent joists rather than stressing the subfloor.
