Section 10.5.1 Minimum Reinforcement of Flexural Members (Non Prestressed)
Equation 10-3 and the 200 bwd/fy criteria are implemented.
Equation 10-3 is calculated using the maximum fc', minimum fy, and maximum d (of all bars on the appropriate face).
bw is taken the core width (see "Concrete "Core" Determination"). If the core width is zero (there is no core), then bw is taken as the width of the section.
The bending strength of the section is designed to be at least 1.2 Mcr. This will only control in odd circumstances such as where the specified cover is extremely large.
Post-tensioning is ignored.
A spacing limit of 3h is utilized in accordance with 10.5.4. For typically sized beams, this limit will not control the amount of reinforcement.
The provisions of section 10.5.2 are not implemented.
