Using a traditional timber framed floor system which includes a sill plate and joists is becoming rare. However, it is still a great way to create the floor system, depending on your project needs. In this detail a stub tenon is used on the post to serve as a locator tenon and a Simpson ST-8 Strap is used to join the post to the sill plate. At the corner joint a simple mortise and tenon is employed to hold everything together with 1 one inch peg. The joists are connected into the sill plate with 1 1/4″ housings and secured with structural screws.
The most painful thing about cutting all this joinery is it will be covered up and you will never see it again after you install your flooring.

Excellent info. Thanks. But how would you fasten, in my case, the sills to 6 concrete piers? One on each corner and two in the middle. It’s just a wood shed.
You can use a simpson strap embedded into the foundation, or a traditional anchor bolt with an access mortise to tighten the nut down. Will try and get some details up.
Thanks
Thanks. Looking forward to any more information. I assume by anchor bolt you mean cast in place I was hoping on just screwing in an expansion bolt or two through the sill into the concrete pier so as to avoid finicky work associated with lining up the cast anchor with holes in the sill. Would like to avoid the strap only because it doesn’t look so good.
That is what I was referring too but your way works well too. Lots of way to do it, no one right way here. Heck, they used to just sit them on stacked stones with no anchors, not that I would do that…good luck with your project.
if only one of the sill pieces is being supported by a concrete wall and the other is spanning between walls, would you span with the purple one or the green one?
The green one would be the better choice.
Do you have any sort of details regarding the anchor bolt to tie down the sill on pier foundation.
I have been constantly mulling this over and I would like to build a finish sauna hut with a timber frame but on piers.
Any suggestions or comments would be greatly appreciated.
Or any thoughts on a beginner doing such a task as well is welcomed.
A simple way to do it is to take the metal strap and embed that into the concrete while you are pouring it and attach the timber to it. You can wrap it around a piece of rebar in your pier. You can also use a Timberlinx A475 at https://timberframehq.com/shop/timberlinx-a475/ and embed the piece of all thread in the concrete for the A475.
