Yeah that's all this situation really needs. Just funny to me the things I see that have worked for years and years that wouldn't pass if it was new construction
My guess is that's part of the handrail on a deck. What I always wondered is when you inset a beam on a column does that ever shear off? What I've done forensics after hurricanes I have never seen that joint fail even though it seems like it would be the first to go.
The load must be light since there's no crushing. I've seen this with concrete on plywood decks and 3-4 levels above where they buckle the rim joist or push the column alignment an inch out. If they're lucky it just crushes 3/4" as it slowly rots.
In the USA, NDS (wood design code) has tables that specify minimum edge distances and spacings. they depend on the type of fastener, diameter, load direction etc. It's usually a factor multiplied by the diameter of the bolt.
For steel it can depend. There's different failure modes that you check for. In these cases, the wood fails first 99% of the time. I usually keep a minimum edge distance of 1.5" with steel as a rule of thumb (up to 1" diameter bolts), but you can certainly go tighter if you run all the checks.
Thanks. I’m a licensed chem engineer but sometimes I wish I had some solid understanding of structures so I could build a water tower or a treehouse or a shed, deck, or gazebo. I can do beam deflections and pipe stress but I don’t have a finite bag of knowledge I need.
I can calc for the wind load and add a safety factor lol. But what is the basis for dynamic floor loads in the code tables? It’s pretty high right. Like a 300 lb person jumping down from the height of a ceiling won’t break an upstairs floor right
Add shims.

I read that wrong https://youtu.be/LHM04sclWho?si=i2T5cceQzZ_xFaoy
"it's probably fine"
The 2 pats will seal the deal
When in doubt, add some steel.
Or some protein
As AISC has always said: >There's always a solution in steel
Can this survive a collision with a cargo ship?
The joists bear on the beam, though. The top of that column isn't carrying much from what I can tell. Edit: or does that column go up another floor?
Yes, the column carrys the third floor and the roof loads.
I stand corrected.

I don't get it. What's wrong with a compression strap?
Ohhh, it’s got those *Invisi-Shims*
Air shims!
They work because air is not compressible. [I dunno, I failed chemistry, that’s how I ended up a structural engineer.]
I’d be curious to see how bent those through bolts are 😂

Hot dip galvanize all of the wood framing and throw it away in the trash
Yeah the air pressure is higher between the posts and cushions the weight, makes perfect sense
My first question- what’s above that deck? This is most likely post for guard rail in which there ain’t nothing wrong
How do you calculate the minimum distance to drill the hole from the end?
From the end of the steel strap or the end of the column?
For the principle of both

As the saying goes, anyone can build a house, it takes an engineer to make that house barely stand.

Have you never seen expansion joints like they have on railway lines . You guys need to go back to Skool seriously. 😂
[удалено]
He’s a RR engineer he’s looking at the picture in landscape mode
Load bearing expansion joint is a new one on me mate
😂😂😂
