# RC Beam Design Criteria

How to create RC beam design criteria controlling stirrups and rebar cover for concrete beam design.

Click **Concrete Design > RC Model Design Criteria > RC Beam Design Criteria** to open the *RC Beam Design Criteria* table.

This table collects design parameters for the concrete beam design process.

You can create as many RC Beam Design Criteria as you need to satisfy the requirements of your design. Once created, you can assign RC Beam Design Criteria to members graphically.

**Label:** A freeform text descriptor that has meaning to you.

**Stirrup Legs:** The number of legs per stirrup.

**Stirrup Size:** The rebar size used for stirrups.

**Edge to Centroid Bottom Bar:** The distance from the edge of concrete to the centroid of the bottom bars.

**Edge to Centroid Top Bar:** The distance from the edge of concrete to the centroid of the top bars.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enercalc.com/e3d-training-manual/design/concrete-design/design-criteria2/beam-design-criteria.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
