Description

The Beam Reinforcement tool allows the user to create reinforcing bars inside a Beam Arch Structure object.

This command is part of the Reinforcement Addon, that you can install with the Addon Manager via the menu Tools → Addon manager → Reinforcement.

The BeamReinforcement tool can be used in macros and from the Python console by using the following function:

)
  • Creates a RebarGroup object from the given structure, which is an Arch Structure, and facename, which is a face of that structure.
    • If no structure nor facename are given, it will take the user selected face as input.
  • l_cover_of_stirrup, r_cover_of_stirrup, t_cover_of_stirrup, b_cover_of_stirrup and offset_of_stirrup are inner offset distances for the stirrup elements with respect to the faces of the structure. They are respectively the left, right, top, bottom and front/rear offsets.
  • bent_angle define the angle of the tip of the reinforcement loop of stirrup.
  • extension_factor define the length of the tip of the reinforcement loop of stirrup, expressed in times the diameter.
  • dia_of_stirrup is the diameter of the stirrup.
  • number_spacing_check if it is True it will create as many stirrup as given by number_spacing_value; if it is False it will create stirrup separated by the numerical value of number_spacing_value.
  • number_spacing_value specifies the number of stirrups, or the value of the separation between them, depending on number_spacing_check.
  • top_reinforcement_number_diameter_offset and bottom_reinforcement_number_diameter_offset are tuple of number_diameter_offset string. Each element of tuple represents reinforcement for each new layer.
   Syntax: (
               "number1#diameter1@offset1+number2#diameter2@offset2+...",
               "number3#diameter3@offset3+number4#diameter4@offset4+...",
               ...,
           )
  • top_reinforcement_rebar_type and bottom_reinforcement_rebar_type specifies type of top/bottom reinforcement bars.
   Possible values:
   1. 'StraightRebar' or 'LShapeRebar'
   2. ('<rebar_type>', '<rebar_type>', ...) and number of elements of tuple must be equal to number of reinforcement
      layers.
   3. [

          ('<rebar_type>', '<rebar_type>', ...),
          ...,
      ]
      each element of list is a tuple, which specifies rebar type of each reinforcement layer. And each element of
      tuple represents rabar_type for each set of rebars.
   4. [

  • top_reinforcement_hook_extension and bottom_reinforcement_hook_extension is the length of hook of LShaped rebars. Possible syntax are similar to as discussed above for top_reinforcement_rebar_type / bottom_reinforcement_rebar_type.
  • top_reinforcement_hook_orientation and bottom_reinforcement_hook_orientation specifies the orientation of LShaped hook; it can be "Front Inside", "Front Outside", "Rear Inside" or "Rear Outside". Possible syntax are similar to as discussed above for top_reinforcement_rebar_type / bottom_reinforcement_rebar_type.
