Included code sections - 3.12.5.1 through 3.12.5.3

Excluded code sections - 3.12.5.4

Reinforcement is provided per Table 3.25, assuming that sections are rectangular and subject to flexure.

Reinforcement is provided such that:

A_sf_y ≥ (0.0013)(460N/mm²)A_c (Amendment 1 and 2)

A_sf_y ≥ (0.0013)(500N/mm²)A_c (Amendment 3)

A_s ≥ (0.0013)A_c

For sections that are not declared as post-tensioned, all post-tensioned reinforcement is ignored.

For post-tensioned beams and post-tensioned one-way slabs, bonded post-tensioning that is on the tension-most side of the cross section centroid, or is within 10% of the cross section depth of the centroid elevation, is considered to be equivalent to un-tensioned 460 N/mm² reinforcement for Amendment 1 and 2, and 500 N/mm² reinforcement for Amendment 3, and will reduce the amount of un-tensioned reinforcement necessary. Bonded tendons at an angle to the cross section will have vector components of their reinforcement areas considered toward the requirement. This interpretation is somewhat more conservative than a literal reading of the code requirements.

User defined reinforcement that is at an angle to the cross section will only have the component perpendicular to the cross section considered.
