# Deck Load \[CSB]

Surface loads to be applied to the deck can be specified by defining the parameters listed below.

## Deck Load

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

**Deck:** Specify the deck on which to apply the loads.

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

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

**Fz (Gravity):** A positive value indicates a load in the global -Z direction (or gravity direction). For typical loads, such as wearing surface loads (with the understanding that this load will be applied to the deck as a whole, while the wearing surface may only cover part of the deck, such as the area between the barriers and in this case, the ***Static Loads - Surface Load*** can be used ), the user should input positive values.

**The Directions of Forces** See the figures provided below for further clarification on the directions of positive forces. ![image-20241215-112416.png](https://openbrim.atlassian.net/wiki/download/attachments/2830762281/image-20241215-112416.png?api=v2) ![image-20241215-112601.png](https://openbrim.atlassian.net/wiki/download/attachments/2830762281/image-20241215-112601.png?api=v2) ![image-20241215-112737.png](https://openbrim.atlassian.net/wiki/download/attachments/2830762281/image-20241215-112737.png?api=v2)

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

```
GET https://docs.openbrim.org/templates/cable-stayed-bridge-workflow/loading-csb/loads-csb/element-loads-csb/deck-load-csb.md?ask=<question>
```

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