Bearing Seat [CUG]
This part can be utilized to define bearing seats between bearings and pier caps. Bearing seats provide a stable surface for bearings to function effectively and can be used to reduce elevation differences between girders. Currently, bearing seats are mainly used for 3D models and 2D CAD. They do not affect FEM, except for potentially changing node elevations. Any stiffness due to the bearing seat is not modeled in FEM.
General
Insertion Points: Used for specifying the bearing location and can be selected by using the three dots and the options 'Pick...' and 'Select...'.
Type [Rectangle/Step]: This parameter is used to define the object type. The available options are Rectangle and Step.
Material: The material definition for the bearing can be made using this parameter. Materials can either be imported or assigned from previously defined ones.
Bearing Seat Steps:
Length: The length is defined by this parameter.
Height: The height is defined by this parameter.
Geometry Option [Flat/Sloped]: This parameter is used to specify the geometry option, with 'Flat' and 'Sloped' available as selections.
Height 1: The height 1 is defined by this parameter.
Width Computation [User Input/Auto]: The options 'Auto' and 'User Input' can be chosen. In the case of choosing the 'Auto' option, the object will be generated according to the pier cap's width along Y-axis. Otherwise, the width of the object will be generated according to the input for the 'Width' column.
Width: If the 'Width Computation' parameter is set to 'User Input,' this column will be activated, allowing the user to specify the width of the bearing seat.
Length: The length of the bearing seat along the X-axis.
Longitudinal Offset: If you intend to adjust the centerline of the bearing seat in the longitudinal direction, use this offset value.
Horizontal Offset: When width computation is chosen as 'User Input', the horizontal offset value can be specified. This value indicates the distance from the center of the insertion point on the Y-axis direction.
Thickness Computation [User Input/Auto]: The options 'Auto' and 'User Input' can be chosen. In the case of choosing the 'Auto' option, the object will be generated according to the distance between the top of the pier cap and the bottom of the girder. Otherwise, the thickness of the object will be generated according to the input for the 'Thickness' column.
Thickness: If the 'Thickness Computation' parameter is set to 'User Input,' this column will be activated, allowing the user to specify the thickness of the bearing seat.
Vertical Offset of Seat Bottom from Top of Cap: This parameter allows adjustment of the vertical position of the bearing seat relative to the top of the pier cap.
Left Start Offset: The offset distance from the left start point of the bearing seat.
Right Start Offset: The offset distance from the right start point of the bearing seat.
Quantities
Volume: The total volume of the bearing seat based on the modeled element definitions.
Weight: Based on the material and element definitions, the weight of the bearing seat is calculated.
Rebar Density (per cubic yard): The rebar density value used for calculating rebar weight.
Rebar Weight: The calculated weight of reinforcement based on the defined rebar density.
Material: Displays the material name assigned to the bearing seat.
IFC
Type [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]: Specifies the IFC entity type for export. Default value is IfcBearing.
Predefined Type [CYLINDRICAL/DISK/ELASTOMERIC/GUIDE/POT/ROCKER/ROLLER/SPHERICAL/USERDEFINED/NOTDEFINED]: Specifies the predefined type attribute for the IFC entity. Default value is USERDEFINED.
Parent [BRIDGE/SUPERSTRUCTURE/DECK/SUBSTRUCTURE/FOUNDATION/APPROACH_STRUCTURE/RETAINING_STRUCTURE]: Specifies the parent structural hierarchy element in the IFC model. Default value is SUPERSTRUCTURE.
Properties:
Ifc Value [Text/Label/Number]: This parameter specifies the IFC Value. The available options are 'Text,' 'Label,' and 'Number.'
Text Value: If the IFC Value parameter is set to 'Text,' its value is defined by this parameter.
Number Value: If the IFC Value parameter is set to 'Number,' its value is defined by this parameter.
Property: The property is specified using this parameter.
Property/Set: The property is specified using this parameter.
