slab on metal deck details 1

[JStructsteel]

anyone have a good detail for a elevated slab supported by CIP wall? Do you embed an angle in the top to weld the steel deck to? Notch the wall?

Thanks

generally a BAR 1/4"x2" with headed studs at 16" o/c grouted into the cores and then puddle welds from the deck to the BAR. No notches...

Dik, its CIP concrete, no cores. This is a residential elevated garage slab. I was going to do steel deck, CIP floor. The more I look at a detail, I think I would expansion anchor a angle into the top of the wall, it can be the pour stop too, and deck can be welded to it. Brick would come down on the outside of the slab. 2x6 wall then can be above slab.

You can use the headed studs with CIP walls, too... Just looked at your detail... the BAR can go on the top of the wall.

Embed threaded anchors, then fasten the angle to the studs. Or, if distance is adequate, you can use post installed anchors.

Metal deck in parking structure is not recommended where I am. Especially if the deck is structural and not just sacrificial formwork.

Road salts and water end up rotting the metal deck really quickly.

jayrod: Definitely not... also for moving forklift equipment, etc.

I typically show a notched wall for my residential ones. Have not got any complaints yet.

While none of these failures ever seems to come to pass in the field, these are the kinds of things that I think about when designer hat is on.

This is a residential garage for a single family home. Brick veneer on outside.

KootK, I think the 3rd detail is mine, except I really wont have the notch since the brick comes down to the top of the wall.

Thanks, I think post installed anchors is the way to go, less coordination. I think I will have some DBAs or HS horizontally from the angle to the slab. It is my diaphragm for the garage.

 

[KootK]

Sure, so it will be the anchors connecting the angle to the wall, loaded in shear and tension, that keep the basement wall from collapsing inward then, correct?
