Best to consult with a structural engineer. nice looking project. How deep did you make those bird's mouth's I would be concerned about the rafter tails cracking.

 

Theres still at least 4 inches of meat left at the thinnest part. But I think between the 1 1/2" of decking above the tails spreading the load and the fact that we dont ever get much of a snow load here everything is ok. (I hope)

 

That looks rock solid. I wouldn't have any concerns about the 6x6, given the fact that it is just a roof structure. The rafters are overcut at the birdsmouths, but the only problem it could cause is some cracking/twisting at the heels. You should secure the heel of the cut to the beam pretty well.

The ridge is supported to the 6x6 that runs perpindicular to it. Are the ends of that 6x6 bearing on the posts or are they butted to the parallel beams supporting the rafter heels? There's some fair load there, and there needs to be some bearing at that point. Perhaps the angle brackets could be let into the post 1" and into the perpindicular 6x6 1", which would actually let the bracket do some structural work.

My only other concern would be the connection between the 6x6 posts and the horizontal structure. There can be a considerable amount of uplift. If they're only nailed or screwed, I'd consider having some 1/4" steel cut, drilled, and painted, and use it to make bolted connections between the two.

 

Rock solid. Right on.

It was too late for me to lower the beams supporting the rafter heels, and I didnt want to let the beam in any for concerns of weakening it. I had to swallow the fact that the birdsmouths were deep, but I'll see if I can sneak in some more fastners to prevent any sort of movement.

The beam that supports the ridge has been notched to the posts with a half lap joint and some lag bolts accompanied by some 3" deck screws. The tiny little king post has been let into both the ridge beam and the support beam beneath it and has been secured with 5" screws.

As for the posts being connected to the beams (read: horizontal structure), the connection was made with an 8"long 3/8" lag screw ( or bolt, depending on where you come from). That means that the lag is penetrating into the post at least 6 inches (due to the half lap joint at connection point over the posts)

Thanks for the 'uplifting' comment. This is the first independent project Ive taken on since learning how to swing a hammer. Im finding it very easy to second guess myself about my abilities and knowledge.

Thanks for your comments

 

From your description of the connections, it sounds like it was done right. Most first time carpenters aren't doing work that looks that good...Trust me, I see a lot of it! :yes:

 

Stressed beams will sag in the middle or bend at the end. Stretch a line and measure the deflections.

With the measured deflection plus knowing the wood type [which gives you the modulus of elasticity] plus the "lumber engineering" book [you borrowed]
http://www.amazon.com/s/ref=nb_ss_gw?url=search-alias=stripbooks&field-keywords="lumber+engineering"
will tell you exactly how much stress the beam is under.

The beam is then its own strain gage.
Using a spreadsheet will keep all the calculations in some kind of order.
:thumbsup:

 

And then you'll have a spreadsheet full of analytical mumbo jumbo...And no solution to any potential problem. :huh:

It is too late to engineer it now, and to do so seems futile. I don't think there's going to be any sort of structural issue with this structure based on the picture and the descriptions posted, and the insignificant loads.

 

Thanks termite. Now that its all together and all the knee braces are up, and Ive hung the deck ledgers and all the other little things I feel a bit more confident with it. Thanks again for the encouragement and advice.

 

I know this is a super old thread but I was curious how this structure held up for you? I was looking to build one just like it. If you're still out there, thanks in advance!

 

Each 6x6 beam only spans 12 feet, of which 2 of those feet are supported by a knee brace. So technically the beams only span 10ft.

I only see a knee brace on the ends, not the long sides.

And those birdsmouth cuts are excessive. Never mind code, they are way too deep to be effective.

 

I would think it will last a long time. The fir 6x6 can hold a lot. Snow loads haven't been mentioned so possibly a issue there. As far as it being square so what. Its more solid than boards nailed together.
