Concrete water tank design
- Thread starter Abdel22
- Start date
How thick are the walls? With thinner walls that cannot anchor standard hooks I've seen diagonal bars across the corner in plan, and sometimes a fillet in the internal face to deal with the corner opening forces. If you do a strut and tie it should be fairly clear where you need reinforcement.

At that thickness I'd imagine you could anchor bars using standard hooks. You'll no doubt be governed by serviceability crack control criteria so tank doesn't leak, so you should have low enough bar stresses at ultimate limit state. Notwithstanding this the diagonal bar is obviously superior but takes a bit more work. There are a couple of pictures in one of kootk's posts in this thread that show the two corner detail options and discusses many other elements regarding the opening joint detailing and design, albeit in the context of a retaining wall. But not fundamentally different to a corner detail in a tank, you'll also have the same detailing issues at the base to wall connection.

I'd say you have the same general issues going on retaining wall vs tank.
But this scenario is also probably more regularly ignored in practice with retaining walls and vertically spanning wall segments are all that's designed and overturning at corners with return wall is argued that it must be better (for overturning). Wall horizontal reinforcement can yield and redistribute horizontally spanning actions to vertical span such that behaviour is closer to an isolated vertical spanning wall with little impact on stability.
If wall was internal to building on inside face then I'd maybe look in a bit more detail due to being an internal space.

the wall is for a loading dock....retain earth and slab on top,,,,that way they can push stuff to bin on other side of wall.
i design it independently, but i want make sure i provide all reinforcement needed for construction
i never come across wall with 90 corner in construction,,,to get a clear idea how they handle it in construction
thank you
