Maximum Span for Shed, without supporting posts??
I am neither a builder or carpenter. I saw a shed today at Home Depot, that measured 16 x 16. It had a loft second story to it for additional storage. There are no internal supporting posts. The joists were 2 x 10, and spanned the full 16 ft width of the shed. I was wondering if a person could use 2 x 12s, and span up to 24 feet without supporting posts? I doubt it. Yet, I walked up into the loft 2nd level and jumped on the floor (I weigh 200 lbs), and the floor felt "pretty" solid. Not rock solid , of course. Of course, going to 24 feet would be 8 more feet of span, and could make a big difference Bottom line, how far can you span with 2 x 10's, and how far with 2 x 12's ? By the way, these joists were 12 inches apart. Thanks for any comments !! --James-- |
