Sleeper Slab [SIG]
For the modeled approach slabs, sleeper slabs can be modeled as a separate object using this object of the workflow.
General
Approach Slab: This parameter can be used to specify the approach slab for which the sleeper slab will be modeled.
Longitudinal Offset: This parameter can be used to define the offset in the longitudinal direction for the sleeper slab. A value of 0 will place the sleeper slab with its center at the downstation-start section of the approach slab. A positive value will offset the sleeper slab in the upstation direction.
Material: This parameter can be used to assign a material to the sleeper slab. Materials can be selected from previously defined options under Properties-Materials or imported as needed.
Length: This parameter can be used to specify the length of the sleeper slab in the longitudinal direction. For a visual representation, refer to the figure provided below.
Width: This parameter can be used to specify the width of the sleeper slab in the transverse direction. For a visual representation, refer to the figure provided below.
Thickness: This parameter can be used to specify the thickness of the sleeper slab in the vertical direction.For a visual representation, refer to the figure provided below.
IFC
Type: The IFC entity type for BIM export. Default is IfcSlab.
Predefined Type: The IFC Predefined Type is specified using this parameter. Available options include:
APPROACH_SLAB (default)
BASESLAB
FLOOR
LANDING
PAVING
ROOF
SIDEWALK
TRACKSLAB
WEARING
USERDEFINED
NOTDEFINED
Parent [Bridge/Superstructure/Deck/Substructure/Foundation/Approach_Structure/Retaining_Structure]: The IFC Parent is specified using this parameter to define the hierarchy relationship in the IFC model.
Quantities
Volume: Based on the definitions provided by the user, the volume of the object is calculated and presented in this column. (Read-only)
Weight: The total weight of the sleeper slab based on volume and material density. (Read-only)
