Form8Dot13AdditionalShearReinforcement(a_s: MM2, n_2: DIMENSIONLESS)

Bases: Formula

Class representing formula 8.13 for the calculation of the minimum additional shear reinforcement in the anchorage zones where transverse compression is not present for straight anchorage lengths, in the direction perpendicular to the tension face.

[\(A_{sh}\)] Minimum additional shear reinforcement in the anchorage zones where transverse compression is not present for straight anchorage lengths, in the direction perpendicular to the tension face [\(mm^2\)].

EN 1992-1-1:2004 art.8.8(6) - Formula (8.12)

Parameters:

  • a_s (MM2) –

    [\(A_{s}\)] Cross sectional area of reinforcement [\(mm^2\)].

  • n_2 (DIMENSIONLESS) –

    [\(n_{2}\)] Number of bars anchored in each layer [\(-\)].
