For sections with multiple values of f ’_c, the minimum f ’_c is used.

The effective depth is determined by a cracked section analysis using the bending moment and axial force in place at time of the shear being investigated. The effective depth is calculated as the distance from the compression most face to the resultant tension force. For cross sections with no reinforcement in tension, a "column style" effective depth is calculated as the distance from the compression most face to the maximum depth of any reinforcement.

When the maximize effective depth option is used the effective depth is first calculated utilizing all reinforcement in the cross section. A subsequent calculation is then carried out utilizing only the reinforcement in the 1/4 depth of the cross section nearest the tension most face, and ignoring any post-tensioning. The effective depth is taken as the maximum of the two calculations. A check is carried out for the latter calculation that there is enough reinforcement to resist the tension chord of a shear truss considering only the flexural moment and shear. If this check fails the results of the latter calculation are not used.

Equations of Table 22.5.5.1 are implemented, including the equations for minimum shear reinforcement (Section 9.6.3.3) for beams.

Section 22.5.3.1 is implemented (but optional 22.5.3.2 is not).

Sections 20.2.2.4, 9.7.6.2.2 and 22.5.1.2 are implemented.

Lightweight concrete is considered.

Minimum reinforcement criteria of sections 7.6.3 and 9.6.3 are implemented

Axial tension and compression are considered in accordance with sections 22.5.6.1 and 22.5.7.1 .

If "beam" torsion design is selected, see Section 9.5.4 Beam Torsion for further requirements.
