Diagonal Reinforcement at the base of conrete wall
Diagonal Reinforcement at the base of conrete wall
(OP)
I could be able to find a clear answer to why diagonal reinforcement is used at the base of the wall (wall-mat interface) other than two places on ACI code One of them is a statement on section R6.4.3 of ACI 350-01 which states that diagonal dowels/reinforcement may be whenever a force transfer is required. And the other is the Figure 15 on ACI 315-99.
From the figure 15 on ACI 315-99, it seems like this is just an engineering practice for liquid containing structures to reduce cracking at one of the most critical regions by providing additional diagonal reinforcement.
I just would like to get your opinion on using the diagonal bars at the base of the wall.
Thanks in advance.

They indicate that these "D" bars are for shear at the base of the stem and shear at the vertical face of the heel at the back of the stem.
In both cases, these bars can be used as Vs bars for the shear check at those locations. Alternatively, you can check if Vc by itself is enough for the shear and/or rely on the horizontal footing reinforcing (for the heel) and the vertical reinforcing (for the stem) in checking for shear using shear friction methods where you would add to the flexural reinforcing the amount of steel needed for shear friction.

I will try to post the figure 15.
