Descrição
The Reinforcement ColumnRebars tool allows the user to create reinforcing bars inside a Column Arch Structure object. This page shows an additional usage example for the tool.
This tool is part of the Reinforcement Workbench, an external workbench that can be installed with the Addon Manager.
Three usage examples are available:
Circular reinforcement inside a column
Utilização
1. Select top face of a previously created Arch Structure object.
2. Then select Column Reinforcement from the rebar tools.
3. A dialog box will pop-out on screen as shown below.
4. Select the Circular Column radio button in column reinforcement dialog.
5. Give inputs for data related to circular column reinforcement.
6. Click OK or Apply to generate circular column reinforcement.
7. Click Cancel to exit the dialog box.
Propriedades
Helical Rebars:
- DadosSide Cover: The distance between rebar to the curved face.
- DadosTop Cover: The distance between rebar from the top face of the structure.
- DadosBottom Cover: The distance between rebar from the bottom face of the structure.
- DadosPitch: The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix.
- DadosDiameter: Diameter of the rebar.
Main Rebars:
- DadosTop Offset: The distance between rebars from the top face of the structure.
- DadosBottom Offset: The distance between rebars from the bottom face of the structure.
- DadosDiameter: Diameter of the main rebars.
- DadosNumber: The number of main rebars.
- DadosAngle: The angular distance between ties.
Scripting

The Reinforcement ColumnRebars_Circular tool can be used in macros and from the Python console by using the following function:
Create Circular Column Reinforcement
RebarGroup = CircularColumn.makeReinforcement(
s_cover,
helical_rebar_t_offset,
helical_rebar_b_offset,
pitch,
dia_of_helical_rebar,
main_rebars_t_offset,
main_rebars_b_offset,
dia_of_main_rebars,
number_angle_check,
number_angle_value,
structure=None,
facename=None,
)
- Creates a
RebarGroup
object from the givenstructure
, which is an Arch Structure, andfacename
, which is a face of that structure.- If no
structure
norfacename
are given, it will take the user selected face as input.
- If no
s_cover
,helical_rebar_t_offset
, andhelical_rebar_b_offset
are inner offset distances for the helical rebar with respect to the faces of the structure. They are respectively the side, top and bottom offsets.pitch
is the parameter that determines how close or far apart each helical loop is to each other.dia_of_helical_rebar
is the diameter of the helical rebar inside the structure.main_rebars_t_offset
andmain_rebars_b_offset
are inner offset distances for the main rebars with respect to the top and bottom faces of the structure, respectively.dia_of_main_rebars
is the diameter of the main rebars.number_angle_check
if it isTrue
it will create as many main rebars as given bynumber_angle_value
; if it isFalse
it will create main rebars at an angle ofnumber_spacing_value
, specified in degrees.number_angle_value
specifies the number of main rebars, or the value of the angle between the main rebars, depending onnumber_angle_check
.

import FreeCAD, Draft, Arch
from ColumnReinforcement import CircularColumn
Circle = Draft.makeCircle(radius=250)
Structure = Arch.makeStructure(Circle)
Structure.ViewObject.Transparency = 80

RebarGroup = CircularColumn.makeReinforcement(
s_cover=20,

helical_rebar_b_offset=40,
pitch=50,

Edition of Circular Column Reinforcement
You can change the properties of the helical and main rebars with the following function:
rebar_group = editReinforcement(
rebar_group,
s_cover,
helical_rebar_t_offset,
helical_rebar_b_offset,
pitch,
dia_of_helical_rebar,
main_rebars_t_offset,
main_rebars_b_offset,
dia_of_main_rebars,
number_angle_check,
number_angle_value,
structure=None,
facename=None,
)
rebar_group
is a previously createdColumnReinforcement
group object.- The other parameters are the same as required by the
makeSingleTieFourRebars()
function. structure
andfacename
may be omitted so that the rebar stays in the original structure.
Exemplo
from ColumnReinforcement import CircularColumn
rebar_group = CircularColumn.editReinforcement(
rebar_group,
s_cover=30,
helical_rebar_t_offset=30,
helical_rebar_b_offset=30,
pitch=60,
dia_of_helical_rebar=10,
main_rebars_t_offset=-30,
main_rebars_b_offset=-30,
dia_of_main_rebars=18,
