A smaller square plate washer eg 75x75x6 or even 50x50x6 should be 'fine'. Outside the code but 'fine' . I say fine because you should check it either by inspection or but rigorous analysis. If the slots are in a hefty 25mm plate I'd likely call it good by inspection with a thick washer.
If...
Typically one would use square plate washers:

And there is a reason why they come in 100mm x 100mm. ;) I wouldn't worry about that extra 2mm, if you are turn the washer 45degrees.
You need to consider it at the edge as you...
I think gut feeling, sanity checks, or a simple test will get you answers quicker that a coefficient of friction calculation.
What you describe there sounds awfully similar to a pallet jack. Moving a 1 tonne load on smooth concrete isn't too hard. Moving a 2500kg load requires a bit of muscle...
Exactly. And in the case of a topping for the purposes of this discussion there wouldn't be an air later between it and the substrate. Sure there might be some trapped bubbles but nothing of consequence.
Crack free? Well surely you would be wanting to look at keeping it in compression. Eg post tensioning.
I think you need to explain the reasons why cracking is a problem. Visual, corrosion, seal etc...
By protecting I presume you mean the intellectual property.
I'm not sure how that is "protected". The "Location, shape, material, etc." is clearly observable on the product. There is no magical trade secrete here, the stability physics here is pretty basic, high school level even. There are...
There are many variations on this theme. It really isn't that complicated. Water pressure holds it down. A leak if any occurs seeps through the wall from high pressure to atmospheric pressure. There is no water pressure on the "dry" side of the barrier.
It just need a low leak seal at the...
Don't fall into the trap of multiplicative safety factors covering the same things.
As soon as you start mixing SF approaches with ASD and/or LFRD you can quickly end up with overly conservative designs.
That said, do take into account the force increase due to the acute angle of the line.
That is a little somber. And given the enthusiasm from many on this forum I'd suggest many here do enjoy their work.
I certainly do.
Why do you need mentorship? You can grow and learn without it.
If you are in a position where you can choose your clients and your work then the world is your...
I'm not sure of most peoples workflow.
But normally there is sufficient difference between an architectural/detailed member model and a structural line model that converting between is normally not the best work flow approach.
Besides the sanity checking process of doing it by hand it very...
The short answer is likely YES. (unless your additional plate is negligible)
The long answer starts getting complicated as you'll need to look at into the complexities of buckling.
But the confusing part of the question is; WHY. If you need a Class 1 or Class 2 section why not just use one...
This is mostly security theatre. Which something authorities often perform. I don't see the engineering failure here.
In this particular case where the risk was more acute then comprehensive security may have been prudent. But that take significantly more planning and resources. Sure there...
I take it this is a home handy man job. This really isn't the forum for this question.... But to give you a quick answer. It really depends on your soil conditions. I'd also question the need for the slab itself. What is its role?
My father and I put a 15,000L (poly tank) on a similar...

Now there is a name I have heard for 30 years!
I think these days it is "Saul Goodman". ;)
I think almost any competent person retraining or entering into another field brings some useful additional skill with them. While I won't...
The above answer is great and straight to the true point.
Though for a more practical answer and easier to implement advice, it might be better to consult relevant connection guidelines with recipes and ready made formulas for what is "sufficiently thick".
Unless you have stiffening gussets...
This by manner accounts seem quite an avoidable tragedy. There are multiple confusing aspects of this disaster both in airline operation and civilworks on the ground.
A good early summary here:
A good view of what the airplane hit here, which seems to be an earth berm covering a significant...
For someone who is an aerospace engineer you don't seem to being able to comprehend the scenario very well.
This basic relevant information is all relatively able to be searched and found on the internet. The weapons systems used and the reasons why it could fly 200 miles before crashing...
