Pinned top??
Pinned top??
(OP)
I have a retaining wall that Im also using as vertical support for a 8ft - 6in slab. Then, can I assume a pinned top for the wall?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

- The connection design.
- Structural layout that will allow a positive load path for the horizontal thrust from the retaining system.
What kind of structure is it? What are the measures that you are taking for the load transfer?

Dowels are then there to transfer lateral load only.

Will ACI allow you to transfer lateral loads via the bars??
I am thinking that you can achieve shear transfer via “shear friction” that will be eliminated by your suggestion of adding a bond breaker.

I have done a similar detail using threaded bars into ferrules at the top of precast walls and have had no problems with it.

Full height of soil behind the retaining wall and any additional surcharge on top of this soil are going to create some force that needs to be considered. You have consider the design capacity of the shear wall, as this force is going to be additive with the seismic force. Also, the global stability of the structure needs to be checked. This lateral force will create additional overturning moment and sliding force on the shear walls.
By thrust, I meant lateral force on the building from the retaing wall.
