2005年10月29日 · 40' bar joists are no problem, nor are 60', other than handling. 40'ers can be as short as 20" and give 127 plf total load. A powder actuated gun with a washer head pin will shoot down the plywood easily. Just don't ever try to get 'em out. I did a 40' span on the last house that got a 300 psf roof. Those were only 30" tall bar joists.

2008年6月8日 · My builder is using 3/4″ plywood roof sheathing that is stamped with a span rating of 40/20. Doesn’t that mean that it is rated to span 40″ in the long […]

2015年10月10日 · I am trying to build a 48'x40' pole barn. I will be using 6x6 poles on 8ft centers with 2x6 framing in between, with 1/2'' osb on the outside. My plan was to nail and glue 2x12's with 1/2'' ply wood in the middle to make a 48ft ridge board "this will be supported by 4x4's and 2x6's". I was planning on using 24ft 2x10 as my rafters on 2 ft centers. "6/12 Pitch". my question is. Is this possible ...

2002年6月13日 · The house will be 40 x 30 , and I need the second story tusses to span the full thirty feet to acheive the open floor we want. I have seen these trusses span that distance, but they where a little bouncy and the sheet rock cracked.

2002年4月12日 · Its a foam system with built in steel beams that can clear span 40 feet (so they say) then your pour your slab on top. My neighbors did the same thing your talking about when they built their house. They hav a full basement under their garage. They used Span-crete then poured about six more inches on top of that (I think six).

2023年3月25日 · Hoping to get some direction and how to complete my vaulted ceiling. I framing my home inside of a metal building so the ceiling wouldn’t be supporting my roof. My area that I’m trying to span is 50×40. I want to span the whole area so the span to the peak would be around 25 ft for each half of the ceiling.

2009年8月19日 · The structure in question here is 20ft 6″ long x 28ft wide. I plan to space I-joists 12 o.c across the width of 28ft for a total of 26 I-joists. I’m using 11 7/8″ I josits. The span that they must span is of course 26ft 6″ (this span includes the foundation wall, outside to outside). The owner plans for carpet on the floor, maybe wood.

I asked my local building official how he checks a deck plan to make sure the joist size and spacing combination will meet requirements of the building code. He goes to the 40 lb. live load floor joist span tables in chapter 7 of the state residential code (based on the 2012 International Residential Code). And that’s just what many deck builders, designers and inspectors have probably done ...

2003年9月15日 · Hi Dan - As I implied, a three span continuous member is a bit more complex than would be three separate beams each supported by simple, unfixed connections at their bearing ends. But that said, I think it would be a somewhat simple matter to reinforce the beam to carry the additional 5 or so feet that would result in moving the one column.
