For a cantilever span (as determined by the declaration of supports in the design strip segment), this criterion is ignored if the section location is outside of L/3 of the support.

For a regular span (as determined by the declaration of supports in the design strip segment), this criterion is ignored if the section location is in one of the two regions between L/6 and L/3 from a support.

For a span with no supports (as determined by the declaration of supports in the design strip segment), this criterion is always applied.

See "Minimum Reinforcement" above for details regarding which slab/beam face (top or bottom) that the reinforcement will have the reinforcement added.

This criterion is never applied to two-way slabs. For strict adherence to ACI 318-99 this criterion should be applied to two-way slabs that do not have a uniform thickness. Under IBC 2003 and ACI 318-02 this criterion need not be used for any two-way slabs.

User defined reinforcement on the appropriate face and bonded post tensioning that is on the tension side of the centroid is counted toward this requirement. Vector components are taken of reinforcement or bonded post-tensioning that is not orthogonal to the cross section.

No check is made to ensure that the structure is post-tensioned.
