I'm a little late to this party. This is certainly an interesting problem and one I've pondered before. My approach would be to:
model the beam with two supports, one at "B1" and the other at "B7" (per the diagram above)
load the beam fully (we'll call this load case A) as well as with only...
I would also not worry about a 1 mm displacement from your analytical model. With both the ceiling and roof diaphragms, I doubt this movement will occur. If it does, I still wouldn't be too concerned.
Wood construction moves through shrinkage and seasonally by more than the 1 mm you're...
I'll second this. Overall your checklist seems fine for gravity loads, but make sure you're not neglecting lateral. I've had a few of these projects where I determined that the wall to be removed was acting as a shear wall and a steel moment frame was needed to preserve the lateral strength.
I agree with the comments above. These plans are rather bad. If this is (or was) new construction, I'm not sure what the "PE" was thinking designating a beam as 6" wide by 15" deep. This would have to be an S section which isn't commonly used in new construction.
If this has already been...
With the steel here, that wasn't the approach I took to resist the outward thrust on my project, but it's a good idea. If the geometry works out similarly and you could rely on direct bearing between the hip and fascia boards, then you would just need a 90 degree bent/welded steel plate to...
No chance a screwed connection like you show will work. Definitely needs to be something more like what kootk drew above.
This is what I came up with for a recent project. Obviously this is a little different than yours because I had a steel frame below the wood framed roof, but I would...
I didn't run any calculations on the anchor bolts, but others here have, and some of them feel they're inadequate. I think that's the reason for this general sentiment. I wouldn't say the design obviously had no engineering oversight, although I think it's possible.
For me, the concern is...
This is impressive architecture. The steel fabrication and overall construction appears top notch. And I really like how it's not connected to the building in terms of a clean waterproofing detail.
With that said, even if it works on paper, I wouldn't be brave enough to design something like...
I do, but it takes maybe 15 minutes to create the agreement/contract. I then use Adobe Sign to have the document digitally signed. I recall my insurance provider inquiring about the amount of work I do without a signed contract, so I try to avoid that.
Well, I'm about 10 times slower than this!
I think the risk is being exaggerated in this thread (see XR250's experience). As long as expectations are properly communicated up front and in a written Agreement, I wouldn't be overly-concerned with being sued. In most cases, the cost of an engineer being wrong will still be less than the...
If you produced the structural plans up front maybe this could work, but I think there's the chance it'll be a nightmare trying to work with a builder who isn't used to using plans. At a minimum, you should be closely observing their work. There will likely be errors which require fixing and...
Even for something small like this, you should have a signed Agreement before doing anything. Most of the CYA verbiage should be there. For a quick house review (don't use the word inspection), it should be made very clear that structural problems may very well be missed by you during the site...
I don't have any experience with this specific industry but I'm also baffled by this. Seems sketchy to say the least.
Again, sketchy!
Maybe it's crazy, but shouldn't you just be able to ask them how they plan to build it? Or I suppose, based on the comments above, they don't actually...
Given the limited information, it's difficult to give a good response here.
Is the load 100 lbs? Then there's probably no issue.
Is the load 100,000 lbs? Then I'd consider strengthening the wall. One option that I've used is to bolt a steel section (like a channel to the wall) with the...
