in_plane_vertical_bending(d: float, area_tension_steel: float, fsy: float, verbose: bool = True) → float

Computes the bending capacity of a reinforced masonry wall element using the methods described in AS 3700 Cl 8.6.

Parameters:

  • d (float) – Effective depth of the reinforced masonry member from the extreme compressive fibre of the masonry to the resultant tensile force in the steel in the tensile zone in mm. Typical values are 95 for 190 block walls

  • area_tension_steel (float) – Cross-sectional area of fully anchored longitudinal reinforcement in the tension zone of the cross-section under consideration in mm². Denoted as Ast in AS3700. Note: the amount of steel used in calculation is limited to effective_area_tension_steel

  • fsy (float) – Design yield strength of reinforcement in MPa (refer Cl 3.6.1), typically 500 MPa

  • verbose (bool) – True to print internal calculations False otherwise

Returns:

Moment capacity in KN

Return type:

float
