# Bearing Load \[SIG]

The loads can be applied to the selected bearing by defining the related parameters below.

## Bearing Load

**Bearing:** Specify the bearing at which the load will be applied. \[Required]

**Stage:** Specify the stage at which the bearing load will be applied. \[Required]

**Fx:** Specify the force applied in elements local X-axis direction.

**Fy:** Specify the force applied in elements local Y-axis direction.

**Fz (Gravity):** Specify the force applied in elements local negative Z-axis direction.

**Mx:** Specify the moment applied around the X-axis.

**My:** Specify the moment applied around the Y-axis.

**Mz:** Specify the moment applied around the Z-axis.

{% 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.

**Loads are applied taking into account bearing rotation angle** The loads defined for the bearings are applied based on the alignment coordinate system for the bearing that has the bearing rotation parameter set to zero degrees. ![image-20241018-091741.png](https://openbrim.atlassian.net/wiki/download/attachments/2720530433/image-20241018-091741.png?api=v2) ![image-20250121-110337.png](https://openbrim.atlassian.net/wiki/download/attachments/2720530433/image-20250121-110337.png?api=v2) ![image-20250121-110539.png](https://openbrim.atlassian.net/wiki/download/attachments/2720530433/image-20250121-110539.png?api=v2) ![image-20250121-110716.png](https://openbrim.atlassian.net/wiki/download/attachments/2720530433/image-20250121-110716.png?api=v2) ![image-20250121-110815.png](https://openbrim.atlassian.net/wiki/download/attachments/2720530433/image-20250121-110815.png?api=v2)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
