# 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]
