What are you using them for? The last time I had seen countersunk bolts that big they were an issue. They kept coming loose due to the traffic vibration.
Is that cast iron? or wrought iron?
Can you salvage the piece and cut off the eye bolt portion. And add a new anchor that you design. So it looks old and original but the new eye bolt is new and surrounded by the old shell.
Goodluck..
I meant code is accepted as the baseline and/or bare minimum. You can of course go above it. And maybe below it if you can prove otherwise. But for any guardrail I would be generous.. especially if it is wood. I see more people falling off balconies/decks than buildings collapsing on them.
In my opinion indep structural reviews are not to nitpick on details and/or flex ur big brain on how efficient the design is (unless you are being asked of course). It is more so a smell test to make sure there is sound loadpath and the concept of the design makes sense. You can of course make...
Well I guess my comment is that many structure pieces are transported by road and are not designed for the effects. Probably because the live load is much more than the dead+inertial loads during transport. But I could be wrong.
fwiw I design large prestressed conc I girders. When shipped they put one end on the semi and strap wheels on the other end. So it becomes a 'trailer'. They def hit pot holes and such at fairly high speeds. Haven't seen any issues so far.
It could be worth sending comments to the association on how this affects delegated designers. I feel if they dont get the questions they will not be able to accommodate or push the AHJ to accommodate.
My sheets are really not that good. And from my experience others find it hard to figure them out.
I think as engineers the hardest part of our job is risk management. You cant get that from a spreadsheet. Anyone can make spreadsheets that crunch the capacity numbers from code equations...
