Description

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:

• Single tie rectangular column
• Two ties six rebars rectangular column (see below)
• Circular column

Two ties six rebars reinforcement inside a column

Usage

1. Select any 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.

Dialog Box for the Arch Rebar ColumnReinforcement tool

4. Select the TwoTiesSixRebars type of column reinforcement from drop down menu on right side.

5. Give inputs for data related to ties.

6. Click Next and the dialog box will be updated as shown below.

Dialog Box for Main Rebars data

7. Select desired rebar type and fill data for main rebars.

8. Click OK or Apply to generate column reinforcement.

9. Click Cancel to exit the dialog box.

Properties

Ties:

• DataLeft Cover: The distance between the left end of the tie to the left face of the structure.
• DataRight Cover: The distance between the right end of the tie to right face of the structure.

• DataBottom Cover: The distance between tie from the bottom face of the structure.
• DataOffset: The distance between tie from the top/bottom face of the structure.
• DataDiameter: Diameter of the tie.
• DataBent Angle: Bent angle defines the angle at the ends of a tie.

• DataDiameter: Diameter of the main rebars.

Scripting

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

Create Two Ties Six Rebars

RebarGroup = makeTwoTiesSixRebars(
    l_cover_of_ties,
    r_cover_of_ties,
    t_cover_of_ties,
    b_cover_of_ties,
    offset_of_ties,
    bent_angle_of_ties,
    extension_factor_of_ties,
    dia_of_ties,
    number_spacing_check,
    number_spacing_value,
    dia_of_main_rebars,
    t_offset_of_rebars,
    b_offset_of_rebars,
    main_rebars_type="StraightRebar",
    hook_orientation="Top Inside",
    hook_extend_along="x-axis",
    l_rebar_rounding=None,
    hook_extension=None,
    ties_sequence=("Tie1", "Tie2"),
    structure=None,
    facename=None,
)

• 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_ties, r_cover_of_ties, t_cover_of_ties, b_cover_of_ties and offset_of_ties are inner offset distances for the tie elements with respect to the faces of the structure. They are respectively the left, right, top, bottom and front/rear offsets.
• bent_angle_of_ties define the angle of the tip of the reinforcement loop of tie elements.
• extension_factor_of_ties define the length of the tip of the reinforcement loop of tie elements, expressed in times the diameter of tie elements.
• dia_of_ties is the diameter of the tie elements.
• number_spacing_check if it is True it will create as many two ties sets as given by number_spacing_value; if it is False it will create two ties sets separated by the numerical value of number_spacing_value.
• number_spacing_value specifies the number of two ties sets, or the value of the separation between the sets, depending on number_spacing_check.
• dia_of_main_rebars is the diameter of the main rebars.
• t_offset_of_rebars and b_offset_of_rebars are inner offset distances for the main rebars with respect to the top and bottom faces of the structure, respectively.
• main_rebars_type is the type of the main rebars; it can be "StraightRebar" or "LShapeRebar".
• hook_orientation specifies the orientation of LShaped hook; it can be: "Top Inside", "Top Outside", "Bottom Inside", "Bottom Outside", "Top Right", "Top Left", "Bottom Right" or "Bottom Left".
• hook_extend_along specifies direction for hook extension; it can be "x-axis" or "y-axis".
• l_rebar_rounding is the parameter that determines the bending radius of the LShaped main rebars, expressed as times the diameter.
• hook_extension is the length of hook of LShaped rebars.
• ties_sequence is the sequence of ties from top to bottom with respect to front view; it can be ("Tie1", "Tie2") or ("Tie2", "Tie1").

Edition of Two Ties Six Rebars

You can change the properties of the ties and rebars with the following function:

rebar_group = editTwoTiesSixRebars(
    rebar_group,
    l_cover_of_ties,
    r_cover_of_ties,
    t_cover_of_ties,
    b_cover_of_ties,
    offset_of_ties,
    bent_angle_of_ties,
    extension_factor_of_ties,
    dia_of_ties,
    number_spacing_check,
    number_spacing_value,
    dia_of_main_rebars,
    t_offset_of_rebars,
    b_offset_of_rebars,
    main_rebars_type="StraightRebar",
    hook_orientation="Top Inside",
    hook_extend_along="x-axis",
    l_rebar_rounding=None,
    hook_extension=None,
    ties_sequence=("Tie1", "Tie2"),
    structure=None,
    facename=None,
)

• rebar_group is a previously created ColumnReinforcement group object.
• The other parameters are the same as required by the makeSingleTieFourRebars() function.
• structure and facename may be omitted so that the rebar stays in the original structure.

Example

rebar_group = TwoTiesSixRebars.editTwoTiesSixRebars(
    rebar_group,                                
    l_cover_of_ties=40,

    t_cover_of_ties=40,
    b_cover_of_ties=40,

    dia_of_ties=8,
    number_spacing_check=True,
    number_spacing_value=10,
