# Segment Construction \[CBS]

Erects the selected segments at a construction stage. Casting and stiffness activation are staged separately, so a freshly cast segment can carry its own weight before it contributes stiffness to the model.

## Segment Construction

**Is Cast-in-place?\[No=0/Yes=1]:** Whether the segments are cast in place rather than precast. Cast-in-place segments use the casting and stiffness stages below to model concrete maturity (default: No=0).

**Stage:** Stage at which the segments are erected.

**Cast Stage:** Stage at which the segments are cast. Applicable for cast-in-place construction.

**Stiffness Stage:** Stage at which the segments begin contributing stiffness to the analytical model.

**Segments:** The segments erected in this stage.

**Age of Segment at Erection(Day):** Age of the segment concrete at erection, used for time-dependent (creep and shrinkage) analysis (default: 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/concrete-segmental-bridge-workflow/construction-cbs/superstructure-construction-cbs/segment-construction-cbs.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.
