ACI 318 Wall minimun Reinforcement
ACI 318 Wall minimun Reinforcement
(OP)
ACI require Cantilever retaining walls to be designed per Chapter 10. This has higher minimum vertical reinforcement requirements than section 14.3.3. What if I have a basement wall retaining soil. My understanding of the code is it goes to section 14.3.3 for minimun reinforcement.
But I think they have the same bending behavior and reinforcement requirements per Chapter 10 for ductility are the same important.
Do I understand the code wrong or their is some difference between Cantilever retaining walls and top restrained retaining walls that I have not think of. Thanks

In a simple span model, the max moment will be in the middle hight of the wall and it will be always bending toward the basement. We still don't want a brittle failure in the wall.

I think what I am trying to say is both the cantilever and top restrain retaining wall has bending in the wall. The only difference will be tension on different face and the top restrained wall might have axial loading on it. I thin k the ductility concept (ACI chapter 10 min reinf. requirement) applies to the top restrained wall as well.
The ACI 14.3 for seems more appropriate for axial loaded walls.
