The Arch Rebar Stirrup.png Stirrup Rebar tool allows user to create a stirrup reinforcing bar in the structural element.


How to use

  1. Create a structure element
  2. Select any face of the structure
  3. Then select Arch Rebar Stirrup.png Stirrup Rebar from the rebar tools
  4. A task panel will pop-out on the left side of the screen as shown below StirrupDialog.png
  5. Select the desired orientation
  6. Give the inputs like left cover, right cover, top cover, bottom, front cover, bent angle, bent factor, rounding and diameter of the rebar
  7. Select the mode of distribution either amount or spacing
  8. If spacing is selected, a user can also opt for custom spacing
  9. Pick selected face is used to verify or change the face for rebar distribution
  10. Click OK or Apply to generate the rebars
  11. Click Cancel to exit the task panel


  • DataFront Cover: The distance between rebar and selected face.
  • DataRight Cover: The distance between the right end of the rebar to right face of the structure.
  • DataLeft Cover: The distance between the left end of the rebar to the left face of the structure.
  • DataBottom Cover: The distance between rebar from the bottom face of the structure.
  • DataTop Cover: The distance between rebar from the top face of the structure.
  • DataBent Angle: Bent angle defines the angle at the ends of a stirrup.
  • DataBent Factor: Bent Factor defines length of stirrup end.
  • DataAmount: The amount of rebars.
  • DataSpacing: The distance between the axes of each bar.


The Arch Rebar Stirrup.png Stirrup Rebar tool can by used in macros and from the python console by using the following function:

makeStirrup(LeftCover, RightCover, TopCover, BottomCover, FrontCover, BentAngle, BentFactor, Diameter, Rounding, AmountSpacingCheck, AmountSpacingValue, Structure, Facename)
  • Adds a Stirrup reinforcing bar object to the given structural object.
  • If no Structure and Facename is given, it will take user selected face as input.
  • Here CoverAlong argument is having type tuple.
  • Returns the new Rebar object.

Example: Creating Stirrup rebar.

import Arch, Stirrup
structure = Arch.makeStructure(length=1000.0, width=400.0, height=400.0)
structure.ViewObject.Transparency = 80
rebar = Stirrup.makeStirrup(20,  20, 20, 20, 20, 135, 4, 8, 2, True, 10, structure, "Face6")

Changing properties of Stirrup rebar.

import Stirrup
Stirrup.editStirrup(rebar, 20, 20, 20, 20, 50, 90, 4, 8, 2, True, 6, structure, "Face6")
