Precast wall to metal deck concrete slab connection

[Redtelis]

Hello!

I am looking to design a connection between a precast core wall & a metal deck concrete slab.

The intention is that the metal deck concrete slab acts as a diaphragm to transfer lateral loads into the precast core wall. More specifically, the idea is to run shear dowels within the precast wall core and these shear dowels to run from the metal deck into the precast core wall and into the precast core landing, see sketch attached. I would like to check with someone if there is an example to design this connection. I assume that the shear dowels should resist the shear lateral forces of the diaphragm. Is there any recommendation of how to design this connection based on Eurocodes??

Weld plates in the precast with a ledge angle to attach the composite metal deck to?

I am not sure if the lateral loads due to wind or not.. In case of seismic, the diaphragm slab is shaken by the shear walls and columns..

My suggestions would be one of the following options;

- Provide keyed joint at wall with hair pin reinf, or insert bended dowels ..

- Provide shear dowels , drill holes at the PC core wall and plant the dowels with epoxy , chipping the PC wall at faying surface will improve the shear friction

Suggest you to look Betonkalender ,Precast Concrete Structures..






I cannot give you the formula for success, but I can give you the formula for failure..It is: Try to please everybody.

@HTURKAK, thanks for the suggestion. I will have a read to the book.

The lateral loads is wind only & notional horizontal forces due to imperfection etc, no seismic.

Dik's solution is far more normal for what I've seen for pre-cast to metal deck. If the loads are only wind and notional, they can't be that enormous, therefore I think Dik's solution is far simpler to implement.
