Progress! Not to ...but you aren't going to block the rest of the joists across the middle? On your support blocks, you could just notch the 4x4's to fit under/behind the 2x6 joist...or were you going for the larger footprint of the 4x4 and 2x6 together?
Yeah, I wanted the larger foot print on the outer middle blocks. Re the center, I need to block them better. IDK about all the way across though. Even without the plywood on, let alone screwed down, it's super solid now. I am going to coat the 4x8 sheets of plywood with some sort of protectant though. All sides so they are protected. I'm not certain if it's rated for outdoor use.
17,500 lbs (+) solid? That plywood helps tie things together a lot as far as side to side...but helps very little with carrying the load across a span.
That's what the joists and the framing are for. It may be 17k, but that's spread out over the entire floor of 8'x10'. I'll need to do some math regarding weight per square inch
If I did my math right, the weight of the wood per square foot will be less than a big dude like myself on my foot print. My two feet are about a foot long each ( go figure ) but side by side they are not 12" wide, so might even be a lot more than just taking my weight on a per square foot rating. No doubt though, it's a lot of weight.
What'd you go, 250#? So 17,500 (that's Ash...green Oak would be more) would be like 70 of you all stacked into that 8x10' spot...each 1 square foot area by itself is fine, but put it all together and the framing has to be able to carry that load to the nearest support...and that support has to be able to carry all that load combined...so you need to calculate the total load on each pier too (more piers are better) Somebody please correct me if I'm wrong!
212.5 per sq ft... That's a lot of load, you will also have snow load that may also drift between the low and high roofs to consider. Wood is a very forgiving building material, so it most likely won't collapse, but as brenndatomu pointed out, your connections will be Taking a ton of load (looks like only 4 lag bolts). Being a structural guy, I would listen to Big Dave. Good news is you won't have to worry about uplift when you get it filled. Everyone always uses this line, I weigh 300 pounds and I am standing in a 1 sq ft area!
I used 2x4 scraps on the back side. Yes, all great points. Seriously, I'm talking everything under consideration. The full stringer support in the middle is a good idea. I also added supports under the first bay, connecting it to the second bay. Yes this is a lot of static weight. I've got no concern about it flying away.
I'll have to weigh him, but he's 17 weeks and I estimate 42-43 lbs. Soon he'll weigh as much as a deck block. Those things are flipping heavy.
More progress. Had a buddy of mine come over and he helped me this late afternoon. All 3 bases done, aside from more blocking. I'll be using a at least a 2x3 or a 4x4 under each center of the bay. This will tie each joist together, and the load will be carried on it as well. I'll need more bricks and concrete blocks, but I don't need any more deck blocks. Good, those are flipping heavy. I tied the first bay, to the second one, and blocked that up on the inside of bay 1. I'll add blocks between the 2x6's as well. I'll do this to the connection of bay 2, to bay 3 as well. As you can see, the 4x4's are up for the corners. I'll be adding more timber lock screws to each 4x4 but I wanted to get them upright while I had help. This thing will be huge. Those 10' tall front 4x4's are tall. I like it.
This thing will serve you well for many years to come. Definitely continue with all the support underneath. Did you put some kind of adhesive between the stacked concrete blocks?
One under each bay center? Or one under each joist? Just to be clear, one last time (just because this is the time to address it, while there is still easy access, and no damage has been done yet) I really feel like EACH joist needs a support block under its middle (of the 8' span) sitting on a least a patio block or two minimum (not sure how those will stand the test of time and pressure, but better than nothing!) I will quit harping on this now...this is your shed, and you are a smart guy, I'm sure you'll do right with the info you have been given, as always! Looking forward to seeing this done...gonna be a cool woodshed! And WOWSERS on the size of the "pup"
You gave some good advice, but I agree, let's just sit back and wait to admire the finished project and hopefully more pictures of the puppy!
