# Single Elements \[CUG]

## **General**

In OpenBrIM, temporary supports can be used for both continuous segments and closure joints. Before adding temporary support, it is necessary to define a **Support Line** that is at the station of the temporary support. Additionally, the **Single Element** doesn’t have a 3D Model. To see the position of the temporary support, users should use the FEA View.

**Girder:** Choose the girder on which the temporary support is constructed.

**Support Line:** Select the support line where the temporary support is constructed.

**Longitudinal Offset From Support Line:** Offset from the selected **Support Line.** Negative values for downstation and positive values for upstation.

## Fixity

Usually, fixed supports are employed for all directions when users do not intend to calculate the stiffness of the temporary tower, etc

**Tx \[Fixed/Free/Stiffness]:** The stiffness in the longitudinal direction is represented by Tx.

**Ty \[Fixed/Free/Stiffness]:** The stiffness in the transverse direction is represented by Ty.

**Tz \[Fixed/Free/Stiffness]:** Tz represents the stiffness in the vertical direction.

**Rx \[Fixed/Free/Stiffness]:** Rotation stiffness in Rx direction.

**Ry \[Fixed/Free/Stiffness]:** Rotation stiffness in Ry direction.

**Rz \[Fixed/Free/Stiffness]:** Rotation stiffness in Rz direction.

## IFC

**Type:** The IFC entity type for BIM export. \[IfcBridge/IfcBridgePart/IfcBeam/IfcColumn/IfcSlab/IfcFooting/IfcPile/IfcBearing/IfcReinforcingBar/IfcReinforcingMesh/IfcTendon/IfcMechanicalFastener/IfcAlignment/IfcPositioningElement/IfcKerb/IfcGuardrail/IfcSurfaceFeature/IfcElementAssembly/IfcCableSegment/IfcSensor/IfcDistributionElement/IfcPlate/IfcWall/IfcRail/IfcRoad/IfcDiscreteAccessory/IfcDistributionSystem/IfcMember/IfcBuildingElementProxy]

**Predefined Type:** The IFC Predefined Type is specified using this parameter to define the structural classification of the element. \[ABUTMENT/ACCESSORY\_ASSEMBLY/ARCH/BEAM\_GRID/BRACED\_FRAME/CROSS\_BRACING/DECK/DILATATIONPANEL/ENTRANCEWORKS/GIRDER/GRID/MAST/PIER/PYLON/RAIL\_MECHANICAL\_EQUIPMENT\_ASSEMBLY/REINFORCEMENT\_UNIT/RIGID\_FRAME/SHELTER/SIGNALASSEMBLY/SLAB\_FIELD/SUMPBUSTER/SUPPORTINGASSEMBLY/SUSPENSIONASSEMBLY/TRACKPANEL/TRACTION\_SWITCHING\_ASSEMBLY/TRAFFIC\_CALMING\_DEVICE/TRUSS/TURNOUTPANEL/USERDEFINED/NOTDEFINED]

**Parent:** The IFC Parent is specified using this parameter to define the hierarchy relationship in the IFC model. \[BRIDGE/SUPERSTRUCTURE/DECK/SUBSTRUCTURE/FOUNDATION/APPROACH\_STRUCTURE/RETAINING\_STRUCTURE]

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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-u-girder-bridge-workflow/superstructure-cug/temporary-supports-cug/single-element-cug.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.
