5 deflection is not adequate to carry the shear, use one or more of the following:

Membrane is considered when the inplane rigidity of the slab is neglected or not contributing to the overall structural stiffness as designed

One-way slabs: The one-way slab is a slab, which is supported by parallel walls or beams, and whose length to breadth ratio is equal to or greater than two and it bends in only one direction (spanning direction) while it is transferring the loads to the two supporting walls or beams, because of its geometry
