I am designing a below grade sump that is 37'-0" by 24'-0" in plan. The controlling wall height is 40'-0". I am analyzing the walls use plate bending theory to get some relief on moment and shear from cantilevered design. What is the concrete shear strength if I am using plate theory as the design basis? Is it 2fc^0.2 or 4fc^0.5? I am not sure if when using plate theory the wall can be considered to fail by one way or punching shear. Or am I totally off base all together?? Do to the wall span and depth shear is controlling and I am trying to minimize wall thickness.
