ReinforcementByDistance(
    diameter: MM, material: ReinforcementSteelMaterial, *, center_to_center: MM

Bases: ReinforcementConfiguration

Representation of a reinforcement configuration given by center-to-center distance. For example ⌀16-150, ⌀20-200, ⌀25-250, ⌀32-300, etc.

Parameters:

  • center_to_center (MM) –

    Maximum center-to-center distance between rebars [mm].

structural_sections.concrete.reinforced_concrete_sections.reinforcement_configurations.ReinforcementByDistance.area property 

area: MM2_M

Area of the reinforcement configuration per meter [mm²/m].

structural_sections.concrete.reinforced_concrete_sections.reinforcement_configurations.ReinforcementByDistance.n_rebars_per_meter property 

n_rebars_per_meter: DIMENSIONLESS

Number of rebars per meter [1/m].

structural_sections.concrete.reinforced_concrete_sections.reinforcement_configurations.ReinforcementByDistance.to_rebars 

to_rebars(line: LineString) -> list[Rebar]

Convert the reinforcement configuration to a list of rebars.

Parameters:

  • line (LineString) –

    Representing the path of the reinforcement in the section. Start of the line defines the first rebar of the configuration, end of the line defines the last rebar.

Returns:

  • List[Rebar] –

    List of Rebar objects.
