# Column Load \[SIG]

Point loads on column objects can be applied based on the definitions made using the parameters listed below.

## Column Load

**Column:** Specify the column to which the load will be applied.

**Stage:** Choose the stage at which to apply the load.

**Distance From Top:** Enter a value to define the location of the load with respect to the start of the column.

**Fx:** Force in the longitudinal direction along the PGL.

**Fy:** Force in the direction perpendicular to the PGL.

**Fz (Gravity):** Force in the vertical direction. A positive value indicates a load in the global -Z or gravity direction.

**Mx:** Moment in the longitudinal direction along the PGL.

**My:** Moment in the direction perpendicular to the PGL.

**Mz:** Moment in the vertical direction.

{% hint style="info" %}
Although **Fz** is applied in the direction of gravity (positive values for **Fz** will correspond to the downward direction, as with gravity), **Mz** will have a positive direction relative to the **+Z** axis or, in other words, in the upward direction.

**The Directions of Forces** For columns with a rotation angle defined as 0, the forces are applied based on the alignment's coordinate system. For columns with a rotation angle defined as a value other than zero, the forces are applied based on the defined rotation angle. See the figures provided below for further clarification on the directions of positive forces. ![image-20250121-113514.png](https://openbrim.atlassian.net/wiki/download/attachments/2348580886/image-20250121-113514.png?api=v2)

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:

```
GET https://docs.openbrim.org/templates/steel-i-girder-bridge-workflow/loading-sig/loads-sig/element-loads-sig/column-load-sig.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
