Add two values for concrete compression

Anonymous — Tue, 18 May 2021 11:43:31 GMT

Hi! I'm new here 🙂

Does anyone know how to add more values of the same parameter to a material?

I want to use the same material, e.g., Concrete C50/60 for the whole life cycle of my project. That means I need to update some parameters depending on the phase I am on.

To better explain, my project has some phases like design, test, evaluation... in the design phase, I will use the value for concrete compression from the Eurocode. After I test the real specimens, however, I want to to assign the concrete compression obtained from the tests to the same material and keep both values on my model.

If this is not possible, can I assign two different materials to the same element (e.g., Beam)?
I would design my beam first with a concrete already inside Revit, that uses the values from the Eurocode, but later I would like to assign a new material with the test values to the same model element.

Thank you in advance!

Welcome. You can add one or more Project parameters to the materials (Manage > Project Parameters). It has to be an instance parameter.

Then it will show up in your Materials Library and you can fill in the values

Hello L.Maas,

thank you! But that is not exactly what I needed... maybe my explanation was a bit confusing.

I would like to add a second parameter for concrete compression (red rectangle), which would be "Concrete Compression measured", for example, and the value would be idk 52MPa and not 50Mpa. But I don't want to simply modify the value directly, I would like to keep them both for documentation purposes.

Do you know if it is possible?
If not, I'll do like you said

No each material van have a single Physical tab and the items therein are fixed.

So what I proposed should be the solution.

The original you could leave in the Physical tab. The 2nd measured value can go into the added parameter. In that case you have both values attached to the material.

Alternatively, you also could add two parameters, instead of using the one in the Physical tab, one original and one measured.

Okay, I understand.
Thank you for your help!
