• The minimum specified concrete cover for nonprestressed cast-in-place slabs is determined automatically according to Table 20.5.1.3.1.

  • Transverse reinforcement is detailed automatically according to 9.7.6.2


Concrete cover for reinforcement is determined according to 20.5.1. The minimum specified concrete cover for nonprestressed cast-in-place slabs is determined according to Table 20.5.1.3.1.

Development lengths of deformed reinforcement is determined according to 25.4. Detailed information: Development of Reinforcement.

Splices of deformed reinforcement is determined according to 25.5 Detailed information: Splices. Minimum spacing of reinforcement s, is determined according to 25.2. Detailed information: Minimum Spacing of Reinforcement.

Maximum spacing, s, of reinforcement required by 7.5.2.3 shall be the lesser of 5h and 18 in.

Flexural reinforcement in nonprestressed slabs

Development of reinforcement is not permitted in critical locations such as points of maximum stress and points along the span where bent or terminated tension is no longer required to resist flexure.

Reinforcement extends beyond the point at which it is no longer required to resist flexure for a distance at least the greater of d and 12db, except at supports of simply-supported spans and at free ends of cantilevers.

Continuing flexural tension reinforcement has an embedment length at least ld beyond the point where bent or terminated tension reinforcement is no longer required to resist flexure.

Termination of reinforcement

At simple supports, at least one-third of the maximum positive moment reinforcement extends along the slab bottom into the support.

At other supports, at least one-fourth of the maximum positive moment reinforcement extends along the slab bottom into the support at least 6 in.

At simple supports and points of inflection, db for positive moment tension reinforcement is limited such that ld for that reinforcement satisfies the rules below.

At least one-third of the negative moment reinforcement at a support has an embedment length
beyond the point of inflection at least the greatest of d, 12db, and ln/16.

Shear Reinforcement

Transverse reinforcement is detailed automatically according to 9.7.6.2, when shear reinforcement is required. Detailed information: Transverse Reinforcement (BRD)

Structural Integrity

At least one-quarter of the maximum positive moment reinforcement should continue to optain longitudinal structural integrity.

At noncontinuous supports, longitudinal structural integrity reinforcement are anchored to develop fy at the face of the support.
