# Moment Releases

How to apply member hinges that prevent moment transfer at member ends while avoiding over-release instabilities.

Moment Releases provide a way to specify that a member has a hinge (no moment transfer capability). They can be applied to the start end, the ending end or both ends of a member, and they can be applied about the local y axis, the local z axis or both.

**Graphical Method**

Moment releases can be defined and assigned graphically by clicking **Create (or Modify) > Member Properties > Moment Releases**. This opens the *Member Releases* dialog, which allows a release to be defined and then assigned to selected members.

**Tabular Method**

Moment releases can be defined and assigned using the tabular method by clicking **Tables > Member Releases**. This opens the *Member Releases* table, which allows multiple member moment releases to be applied at once in the table.

**Caution!**

Use caution not to "over-release" when applying member releases, as this can lead to model instabilities. For example, picture two members connecting at a node. If the intent is to model a hinge at that location, then only ONE of the two members should have a release applied, because it only takes one release to prevent the transfer of moment. If BOTH members were released, it could cause a stability problem, because that common node is now disconnected (in a moment transfer sense) from ANY member in the model. So mathematically, it is able to spin, and this causes an instability in the mathematical solution of the model.

## 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.enercalc.com/e3d-training-manual/building-the-model/properties/properties-for-members/moment-releases.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.
