Composite column definition error in ETABS

[member 1218881]

Hello, I want to design Etabsta concrete filled composite column. I cannot add reinforcement when defining from normal composite sections. (version 22.1) Therefore, I want to design the composite column containing concrete-filled reinforcement from the section designer section (SD). However, this time, even though I marked the composite column, it sees the column as steel. When I want to define a composite from the Design section, it gives the error "wrong material available".

I see the moment curvature graph of the concrete-filled composite column only when I can place reinforcement. Why does this error occur in Etabs and how can I solve it? I am waiting for your urgent support.

When designing concrete-filled composite columns in ETABS, particularly in version 22.1, several factors can contribute to the errors you are encountering.
1. In your case, a concrete-filled composite column consists of a steel section filled with concrete, which enhances its load-carrying capacity.
2.The error message “wrong material available” suggests that there may be an issue with how materials are defined within your model.
3. You have correctly defined both the steel and concrete materials in your project
4. The material properties (like strength, density, etc.) conform to the requirements for composite design.
5. Make sure you select the correct type of section (i.e., composite) when defining it.
6. If reinforcement is not added or recognized, ETABS may default to treating the section as purely steel.
7. Go to the reinforcement tab within Section Designer and ensure that you add appropriate reinforcement detailing.
8. Verify that you are using compatible bar sizes and types that meet code requirements.
9. Ensure all components are correctly assigned and that there are no missing links between sections.
10. Sometimes bugs or issues can be resolved by updating to the latest version or patch of ETABS.
11. Consider reaching out directly to technical support from CSI as they can provide specific guidance based on your project setup. By ensuring proper definitions and configurations within ETABS, you should be able to successfully model your concrete-filled composite column without encountering material-related errors.
