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.

12.7.2 Spacing

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

Maximum spacing, s, of deformed reinforcement is the lesser of 5h and 18 in.

12.7.3 Diaphragm ad collector reinforcement

Diaphragms which are part of floor or roof designed according to one-way and two-way slab reinforcement detailing automatically.

One-way slabs are provided the rules explained in One-Way Slab Reinforcement Detailing. Two-way slabs are provided the rules explained in Two-Way Slab Reinforcement Detailing.

Reinforcement provided to resist tension extends beyond the point at which it is no longer required resist tension at least ld, except at diaphragm edges and at expansion joints.
