On what norms is rebar based in Revit? For example the bending radius

[1031419]

I am writing a paper for my internship on why they should or shouldn't start modeling rebar in 3d at this firm. One of the concerns of my supervisor is whether the rebar modelled in Revit automatically bends according to the norms we use. I have figured out that they do follow the norm for specifically the bending radius (see the images below), but does someone know where i can find all of the norms used when programming rebar into Revit?

The top image is made by a rebar supplier and the bottom image is made in Revit

Thank you very much

Revit Rebar shapes are typically based on the regional install and the local codes and guidelines.

In previous versions there was more Standards/Code specific references but the formulas still remain in the families.

There are Third Party addin which provide code referenced rebar families which you simply install and override the Revit default families.

There are a lot of companies who are using Revit for Rebar, primarily in coordination models where clashing and interference checks are critical. Also for more BIM related project it may be a deliverable requirement as part of your design service so unless you can offer this you cannot tender for the project.

If you take a look at:

Sofistik

CADS RebarCAD 3D

Graitec

Specifically for their Revit Rebar Addin functionality they will have some case study information which may help with your paper.
