# Story Drifts

How to define drift nodes and report nodal displacement, inter-story drift, and drift ratios for each story.

The first step in evaluating story drifts is to define Drift Nodes, which are the nodes at which drift will be evaluated. To do this, select the drift nodes and click **Create > Story Drift Nodes**. This will create a table of nodes (usually one at each level) that can be viewed by clicking **Tables > Story Drift Nodes.**

After selecting the drift nodes, click **Analysis Results > Story Dr**i**ft**. The *Story Drifts* table opens.

Select the desired Load Combination.

Since this table uses the predefined drift nodes, deselect the option to show selected entities only.

The table reports nodal displacement, inter-story drift, and the drift ratio in the X and Z direction for each story.

The table can be printed with the Print button.

## 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/analysis/reviewing-the-analysis-results/story-drifts.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.
