ladder on foundation wall, no sill
Up here we build foundation walls with a ladder system. How do I set up X1 to do that for me?
Thanks, Rudi---------------------------

What is a ladder system? Could you post a pic or section view perhaps?

Rudi, I usually just add the ladder height to the stemwall and show the ladder in section with cad. You can model it with joists or make a symbol if you need to.
(Ladder is a term we use for a double vertical mudsill. Often they are prebuilt, looking like a ladder with the blocking joining the verticals.)Rob Fisher

Thanks Rob, I thought there might be a check mark to get that done. Is that a point of consideration for future chief updates?

Thanks Rob. I presume the joists then stack on top of that?

Never heard of this type of foundation on this forum so I doubt if CA
has it on their to-do list.
you probably should post a thread in the suggestions section with a link to this thread

Rob,
Interesting. Is there a horizontal plate on top of the two vertical "sills? Are they side by side like a double 2x header? I guess not if there's a ladder? Got a detail?
Can you add the total hgt to the mudsill spec in the foundation defaults dbx?

Rob,
How long are the ladder "rungs"? I would assume just enough for the entire assmebly to span the thickness of the foundation wall?
How are these assemblies attached to the foundation? Plate at the bottom of the assembly?
Very interesting.

We got some very good pictures from our last job. Will post them tomorrow. Thanks everyone for chiming in... I suppose we do stuff differently up here in Alberta

Some advantages of ladder mudsills:
1. Allows for interior attachment, joists can be fastened to the inside sill as well as the rim joist. Interior strapping walls can also be attached.
2. 2x6 ladders can be used with 1 1/2" of ladder below top of a standard 8' form (for attachment), extending stemwall to 8'-4". The stiffeners are usually 4' o/c.

So they are poured into the concrete then? Looks like ties in the section view. Am I correct the your joist is bearing directly on the concrete?

Yes. Joists are bearing on the imbedded mudsill, the conc is usually left down a bit.

Minimum bearing length is 1-3/4" with I joists. Do you do anything to address that? Bearing plate?
I'm just interested, never seen this method.

Good question Rusty .... maybe the embedded members should be 1-3/4" min. thickness for the min. bearing. Either that or there should be a non-wood products shim over the concrete. That sure ends up being a thick foundation wall! I am curious as to what the real benefits of such a method is? Maybe Rudi or Rob can expound a bit more on this. Since concrete, at least here in the states, is still quite high in price, this seems like a costly system, especially if it is used for basement walls. And Edmonton, the last I checked, is a couple hundred miles north of the North Pole and has real winters and everything.
