How to read a Span Table???

[MossflowerWoods]

I would also suggest to check the zoning code on the number of "accessory" buildings you are allowed--sometimes it is only 2!

I'm sorry you are breaking up [crackle] I can't quite hear you [static]...
:laughing:

All of the others the prior owner built are slated for demolition...:thumbsup:

Hey, Dave.
Here's the way I used to set the Simpson post bases (4"x6") and concrete footings (18"x18" x 22" deep) for the 20x28 ft equipment shed I built a few years ago. Got it level using a bunch of 10 ft 2x4s and a 4-foot spirit level

CrazyAl,
I have never built with the concrete blocks and I don't understand how to level them (or how to keep them level over time and various moisture etc levels). I can see the simplicity, especially the ones with the X to cradle the joists. I can see just laying out 15 of those and I'm DONE, but I don't know how to do it...

I know this may be a tad late...but I jut stumbled onto this link and though about your building project. It's a link to an online article from Fine Home Building and using bricks/blocks for what you're considering.

The one thing they don't address though, is high wind attachment.

Good luck with your project...

Had great clarity for me! It answers a couple of questions!

Thank you!

STUPID QUESTION!

I cannot buy a 20' 2x8 (at least I have not found one).

So how do I build a 20 x 10 base for the floor joists?

HELP!

I'm working up my plans!

If you have a menards in your area, I know they stock them.

And lumber yards can usually get them as well, but be prepared $$$$.

Box stores like HD and lowes usually dont and cant get anything over 16'.

But what you could do is put a mid span of posts in, and use two shorter boards. like 2 10'ers. But if they are load bearing, (I am not sure exactally what your design is) I would use 2 12' boards to give you a 4' over lap and nail them together and support @ 10' from below.

LD1,

No Menard's, I checked. Ohio is the closest store.

I have to go to ProBuild to check out the Advantech floor boards so I will see if they can get me a 20' 2x8. I only need 2 of them after all. How expensive can they possibly be...

Everything else is pretty much 10' or less.

I think I pretty much have no choice...

Thanks,
David

Can you run your joist the other direction (the 10' way)? Use a double Timberstrand type rim board to support the joists. Otherwise splice on a supporting pier as LD1 states.

RippySkippy,

Unless I'm misunderstanding things, I need to make a 20x10 box, and hang the 10' (9' 9") joists inside it.

My concern is the outer 4 boards, two at 10' and two at 20'. I did not want to kluge the outer frame.

Make sense? Am I goofing this up?

I think you are going to have to kluge it up:confused2:

Are you still going the post route?? If so, just put one in the middle there @ 10' and use 2 10'boards. And since these RIM boards are going to be supporting the joists, I dont think a 2x8 rim will handle ALL the joists and weight of the load IF they are only supported 10' appart.

So if I am picturing this correctly, the 20' board will need 5 supports, every 5'. Wether it be 4x4's or peirs. And spanning the full 10' with the 2x6's on 12" centers is pushing it as well. I hope you plan on still running a mid support as well so the effective span distance of the joists is only 5' for them 2x6's.

And FWIW, a PT 2x8x20 up here @ menards is $16.49 to give you an Idea.

10'ers are 5.92ea
