# Dynamic Loads \[STG]

OpenBrIM allows users to analyze the structural behavior of a modeled bridge under dynamic loads.

The Response Spectrum Curve object can be used for this purpose. The Response Spectrum Curve is a graphical tool that represents the maximum response of a range of oscillators (simple harmonic oscillators) to dynamic loads, such as seismic activity. It plots natural frequency (or period) on the X-axis and peak response (acceleration, velocity, or displacement) on the Y-axis.

Additionally, Eigenvalue analysis and RSA can be utilized to evaluate the structural behavior of a bridge under dynamic loads.

For a detailed explanation of each library object, refer to the relevant section of the documentation.

## 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/steel-tub-girder-bridge-workflow/loading-stg/loads-stg/dynamic-loads-stg.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.
