# Surface Load (on wall face) \[RW]

Applies a distributed pressure to the stem face or to the top of the footing of a wall segment.

## General

**Wall Segment:** The wall segment the load is applied to.

**Stage:** Construction stage at which the load is applied.

**Loaded Face \[Stem (vertical)=0/Footing Top (horizontal)=1]:** Selects which surface the pressure acts on — the vertical stem face or the horizontal top of the footing (default: Stem (vertical)=0).

**Variation \[Uniform=0/Linear=1]:** Whether the pressure is constant over the face or varies linearly across it (default: Uniform=0).

**Magnitude (top / start). For Stem: at TOW. For Footing: at toe side.:** Pressure at the start of the variation — at the top of wall for a stem load, or at the toe side for a footing load (default: 0).

**Magnitude (bottom / end). Used only when Variation=Linear.:** Pressure at the end of the variation. Applicable only when Variation is Linear (default: 0).

**Load Direction \[Normal to face (inward)=0/Gravity (-Z global)=1]:** Direction the pressure acts in — perpendicular to the loaded face, or vertically downward in global coordinates (default: Normal to face (inward)=0).

## 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/templates/retaining-wall-workflow/static-loads-rw/surface-load-on-wall-face-rw.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.
