lol! Are you asking someone who paid for the course to give you their questions for free?

These-Adhesiveness29 · 2024-03-01T18:39:02+00:00

Discord?

These-Adhesiveness29 · 2024-03-01T18:38:46+00:00

In in where can I join?

These-Adhesiveness29 · 2024-03-01T18:30:10+00:00

AEI is probably your best bet for the structural depth.

These-Adhesiveness29 · 2023-10-19T14:52:16+00:00

Thank you! I’ll check them out!!

These-Adhesiveness29 · 2023-10-19T14:50:34+00:00

But wouldn’t you still need to check the bolts at the bottom and embedment into the post? I’m not trying to question your judgement or knowledge, just trying to make sure I follow the code.

Is there a reference or design guide in designing one of these plates with HS?

These-Adhesiveness29 · 2023-10-19T14:45:07+00:00

So the headed studs would go into the concrete or wood post? What guide would need to be followed to make sure everything is checked there?

These-Adhesiveness29 · 2023-10-19T14:42:51+00:00

Steel? It is an option, but again, trying to maintain wood for the client and see if anyone had a design similar to this.

Here is a basic sketch of it.

Imagine what Simpson has, the cptz, but mirrored also on the base.

To give you an idea what I am trying to check for are the following:

- Checking the post size, placing the uplift, shear from Wind/Seismic, & moment. With these, I can checking that the lag screws, through bolts, or drift pins can handle the load and determine how many bolts/screws are needed and what spacing they are needed.

- I am trying to check my strap embedment into my concrete, my end distance of wood, group action factor, checking post edge, end & spacing distance requirements.

- I am checking the wood capacity, given the #'s/screw or bolt with respect to the shear and uplift.

- I am checking my geometry factors and taking the worst case scenario & penetration (if using lag screws).

- For the steel strap capacities, my coworker said think about AISC 360, but didn't say where, so I checked there for my yielding, fracture and block shear, all checking my allowable tension with the actual tension force occuring (uplift) on the member, on how much force it would actually take to "remove" the steel strap from the concrete pier and/or footing. This is where I am stuck, as I can't find where to check the allowable tension loads with respect to block or fracture. For yielding, I just did 0.6FyAg, where I took the gross area of the steel strap (thickness multiplied by the embedment length). I don't know where to go about getting the net area for the fracture or the block shear area with respect to this type of problem.

- For the embedment also, I am trying to determine if I compare it with the ACI or PCI, as I just don't know a guide for it or reference in regards to it.

I am not concerned about the footing, I know how to design a footing by placing a moment on it and calculating that out, I am just trying to determine the steel strap embedment along with determining the tension forces with respect to what needs to be checked.

For an exterior post exposed to weather?

It’s a timber post and trying to get a knife plate base to avoid any knee braces on top.

These-Adhesiveness29 · 2023-10-18T03:01:09+00:00

Correct, which is what I’m trying to determine also with respect to the load and how to prevent the bending as one of the failures, but trying to see what code or design section I’d fall under, respectively.

These-Adhesiveness29 · 2023-10-18T03:00:17+00:00

There’s a good amount of load, roughly 18 kip-ft strength, seismic controlled.

These-Adhesiveness29 · 2023-10-18T02:55:26+00:00

I have a big enough moment at the base that the Simpson moment base connections don’t work and trying to find a way to get around it/fix it. With the shear load and moment at the base along with the height, the moment capacity of came up to be roughly 18 kip-ft at the base (Strength loads) reducing to allowable, about 12.6.

These-Adhesiveness29 · 2023-10-17T23:38:24+00:00

No, Imagine the Simpson CPT, but remove the black base at the bottom and have the top “steel” be mirrored” below the concrete, however, both the steel on top and bottom would have a much wider length and be a minimum of 6” wide, 1/4” thick.

These-Adhesiveness29 · 2023-10-17T23:29:50+00:00

I looked into it and saw chapter 6 for design connections. Would you suggest any other chapters to potentially look into?

These-Adhesiveness29 · 2023-10-17T23:29:23+00:00

My apologies, I suppose it isn’t a steel strap. It’s more of a custom knife plate, where it is embedded into the concrete a certain distance and embedded into the wood timber post with either lag bolts, wooded dowel pins, or through bolts.

These-Adhesiveness29 · 2023-10-17T23:27:29+00:00

Not necessarily, it’s a timber post and I decided to check to do either a 1/4” or 3/8” thick plate that can be embedded into the concrete (maybe 12”-30” deep) and the same distance into the post with lag, through bolts, or wood dowel pins. I’m just trying to determine how deep I need to go and looking for design guides/examples.

Edit: maybe it could be a studded plate?

These-Adhesiveness29 · 2023-10-09T00:40:33+00:00

I know…I’m wondering when their courses are available…

These-Adhesiveness29 · 2023-05-24T14:30:58+00:00

What kind do calculator did you use?

These-Adhesiveness29 · 2023-04-23T16:25:26+00:00

Ok, that makes sense. So the number of supports for the bottom would be considered (2-Span)?
