# Transverse Live Load On FELines \[FEA]

Applies a transverse live load across a set of finite-element lines, positioning wheel loads and lane loads to produce the governing transverse effect. Multiple presence factors are applied according to the number of loaded lanes.

## Inputs

**FELines:** The finite-element lines the transverse live load is applied to.

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

**Axle Load:** Magnitude of a single wheel/axle load (default: 16).

**Lane Load:** Uniformly distributed lane load applied alongside the axle loads (default: 0).

**Max. number of lanes\[1 Lane=0/2 Lane=1/3 Lane=2/4 or More=3/No Limit=-1]:** Caps how many loaded lanes are considered when searching for the governing arrangement. **No Limit** lets the search use as many lanes as fit (default: No Limit=-1).

**Multiple Presence Factors:** Multiple presence factors applied by number of loaded lanes, in order (default: 1.2, 1, 0.85, 0.6, 0.6).

**Distance between Wheels:** Transverse spacing between the two wheels of an axle (default: 72).

**Minimum Distance between Vehicles:** Minimum transverse clear distance enforced between adjacent vehicles (default: 24).

**Alignment Direction\[X-Direction=0/Y-Direction=1]:** Global axis the alignment runs along, which fixes the transverse direction the load is swept in (default: Y-Direction=1).

**Unit Load Spacing:** Transverse increment the load pattern is stepped by while searching for the governing position (default: 36).

## 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/openbrimfea/live-load-fea/transverse-live-load-on-felines-fea.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.
