Dear concreteok, why you design your basement wall with deep beam assumption? Is it for the wall on middle section of your basement or for the edge wall ? In deep beam theory, the beam only support with simple support or continous support as laboratory tested. They are no supported/restrained by soil and have no lateral load like soil pressure or seismic. If you have a big vertical load from column above, you can assumption a part of the wall below the load as column for example 1 meter width, still check dimension requirement. And calculate the number of pile below.
