# End/Interior Bent
This section defines the end bent (abutment cap) geometry, including cross-sections, elevations, and FEA settings.
{% hint style="info" %}
**Navigation:** Substructure > Pier > End/Interior Bent
For detailed parameter explanations, see the [End/Interior Bent Reference](https://docs.openbrim.org/templates/precast-i-girder-bridge-workflow/substructure-pig/endinterior-bent-pig).
{% endhint %}
## Steps
### Step 1: Navigate to End/Interior Bent
Navigate to **Substructure > Pier > End/Interior Bent** in the tree view.
### Step 2: Set Location and Name
Click the **three-dots icon** on the **Location** cell and select **Abut1** (End Bent). Enter the name as **EndBent1**.
### Step 3: Define Section
Click the **three-dots icon** on the **Straight - Tapered Section / Length** cell and select **Edit**.
### Step 4: Assign Start and End Sections
Click the **three-dots icon** on the **Start Section** cell and select **Rectangle\_exist\_EBcap**. Repeat for the **End Section**.
Enter **Section Length** as **36 ft** along Y-Y starting from right.
### Step 5: Set Slope Option
Navigate back to the **General** tab and set **Slope Option** to **Alignment**.
### Step 6: Set Elevation and Offset
Enter the **Top Elevation Offset from Alignment** and **Transverse Offset** values as shown.
### Step 7: Configure FEM Settings
Navigate to the **FEM** tab and select a section for **Rigid Section**.
### Step 8: Create Additional End Bents
Repeat the previous steps to create end bents at other locations (e.g., **EndBent2** at **Abut2**).
Quick Tip: Transverse Offset Direction
Offset values use the Profile Grade Line (PGL) as the reference point.
## Verification
{% hint style="success" %}
After completing these steps, your end bent configuration should match the views shown below.

## 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.openbrim.org/examples/concrete-bridge-examples/example-prestressed-i-girder-concrete-bridge-ex1-pig/substructure-ex1-pig/endinterior-bent-ex1-pig.md?ask=&goal=
```
`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.
