Anchorage of bottom reinforcement at end support.

Treat as a solid slab and retain not less than half of the mid-span reinforcement.

Use 2T12 L bars bottom at end support

Anchorage force for this reinforcement with zero design axial load a, x where

For vertical shear reinforcement calculated by the standard method

a, = z(1 - cota)/2 < 0 a = 90° and z is taken as 0.9d

Although this ribbed slab falls outside the solid slab classification requirements for analysis, treat as a solid slab for detailing and take a, = d.
