Retaining Wall Segment [RW]

The Retaining Wall Segment is the primary object of this workflow. Each segment models one continuous run of cantilever retaining wall between two stations: its stem, its spread footing, an optional footing key, and the analytical shell model used for design.

General

Structure Definition: The retaining wall structure this segment belongs to. The segment takes its alignment and station reference from the selected structure.

Segment Start Station: Station along the layout line where the segment begins (default: 0).

Segment End Station: Station along the layout line where the segment ends (default: 240).

Wall Material: Concrete material assigned to the stem and footing of the segment.

Segment ID: Identifier used to label the segment in drawings, reports and quantity take-offs (default: S001).

Orientation [Left=1/Right=2]: Side of the layout line the retained soil sits on, which fixes the direction the stem faces (default: Right=2).

Standard Plan Type by Design H [Custom=0/6ft=1/8ft=2/10ft=3/12ft=4/14ft=5/16ft=6/18ft=7/20ft=8/22ft=9/24ft=10/26ft=11/28ft=12/30ft=13/32ft=14]: Selects a standard-plan wall type by design height. Custom leaves every stem and footing dimension under user control; choosing a standard height drives those dimensions from the corresponding standard plan (default: Custom=0).

Stem

Top-of-Wall Thickness: Stem thickness at the top of the wall (default: 12).

Batter (1 in X) [Vertical=0/]: Batter of the stem face, expressed as 1 horizontal in X vertical. Enter 0 for a vertical stem (default: 6).

Has Stem-Top Haunch [NO=0/YES=1]: When YES, a haunch is formed at the top of the stem to seat a barrier (default: YES=1).

Haunch Seat Width (barrier seat at top of wall): Width of the barrier seat formed by the haunch (default: 18).

Haunch Height (below top of wall): Height of the haunch measured down from the top of the wall (default: 12).

Haunch Bottom Chamfer Horizontal: Horizontal leg of the chamfer at the bottom of the haunch (default: 6).

Haunch Bottom Chamfer Vertical: Vertical leg of the chamfer at the bottom of the haunch (default: 6).

Footing

Bottom of Footing Elevation: Elevation of the underside of the footing, in the global coordinate system (default: 0).

Footing Toe (exterior face to near edge): Distance from the exterior face of the stem to the near (toe) edge of the footing (default: 24).

Footing Heel (exterior face to far edge): Distance from the exterior face of the stem to the far (heel) edge of the footing (default: 96).

Footing Thickness: Thickness of the footing (default: 18).

Has Footing Key [NO=0/YES=1]: When YES, a shear key is cast under the footing to increase sliding resistance (default: NO=0).

Footing Key Depth: Depth of the footing key below the underside of the footing (default: 12).

Footing Key Width: Width of the footing key (default: 12).

Footing Key Offset (from closest toe edge): Distance from the toe edge of the footing to the near face of the key (default: 36).

FEA

Generate FEM [NO=0/YES=1]: Setting this to NO disables the analytical (finite-element) representation of the segment (default: YES=1).

Mesh Size: Maximum finite-element size used when meshing the segment (default: 60).

Mesh Algorithm[MeshAdapt=1/Automatic=2/Initial mesh only=3/Delaunay=5/Frontal-Delaunay=6/BAMG=7/Frontal-Delaunay for Quads=8/Packing of Parallelograms=9/Quasi-structured Quad=11]: Meshing algorithm used to generate the shell mesh of the segment (default: MeshAdapt=1).

Reinforcement

Show 3D Rebar [No=0/Yes=1]: When Yes, the reinforcement is drawn in the 3D view (default: No=0).

Referencing Objects

Barriers on this Segment: Barrier objects hosted by this segment. (Read-only)

Piles on this Segment: Single Pile objects that reference this segment. (Read-only)

Quantities

Total Volume: Concrete volume of the segment. (Read-only)

Total Weight: Concrete weight of the segment. (Read-only)

Material: Material reported for the segment in quantity take-offs. (Read-only)

Rebar Calculation Method[By Density=0/By Length=1]: Chooses how reinforcement quantities are estimated — from a rebar density per unit volume, or by summing explicit reinforcement lengths (default: By Density=0).

Rebar Density(per cubic yard): Reinforcement weight per cubic yard, used when Rebar Calculation Method is By Density.

Rebar Weight (By Density): Reinforcement weight computed from the density. (Read-only)

Stem Rebar Length: Total length of stem reinforcement. (Read-only)

Stem Rebar Weight: Weight of the stem reinforcement. (Read-only)

Total Rebar Length (By Length): Combined stem and footing reinforcement length. (Read-only)

Total Rebar Weight (By Length): Combined stem and footing reinforcement weight. (Read-only)

IFC

Type: IFC entity used when exporting the segment. Default IfcWall.

Predefined Type: IFC predefined type. Default RETAININGWALL.

Parent: IFC parent the segment is attached to in the export hierarchy. Default RETAINING_STRUCTURE.

Reinforcement Data

Stem Reinforcement Rows: Table of reinforcement rows in the stem. Each row defines a rebar layer used for capacity computation and detailing.

Footing Reinforcement Rows: Table of reinforcement rows in the footing. Each row defines a rebar layer used for capacity computation and detailing.

Rebar Render Segments (tube facets): Number of facets used when drawing rebar as tubes in the 3D view. Higher values look smoother and render more slowly.
