Place Sleeper Slab
To place a Sleeper Slab supporting the approach slab at the start and/or end of a bridge use the following procedure.
You must use an existing Sleeper Slab template. Your model must have Approach Slab defined before placing a Sleeper Slab.
- On the Home ribbon tab, select the Place Sleeper Slab tool in the Approach Slab group.
- Check Place options for either start and/or end of bridge.
- Select the template to use.
- (Optional) Horizontal Offset, transverse offset if any.
- (Optional) Longitudinal Offset if any.
- (Optional) Conform Backwall with Approach Top, for L or T shaped abutment backwalls to follow slab top shape.
- (Optional) Conform with Approach Bottom, if the ledge needs to follow the bottom slope of the slab
- (Optional) Clear the Add Constraints check box if no additional placement constraints are required.
- (Optional) Apply Skew to Solids, so the ends are squared off in line with the slab.
- In the view window, data
point to accept, and see the sleeper slab solid placed.
If you checked the Add Constraints option, then the Solid Constraints Definition dialog opens.
- (Optional) Specify any necessary point or variable constraints along the deck and then click Apply.
- If variable constraints are being specified, the template tab shows the effect of the variations defined at user defined distance (use the slider or enter cross section distance).
While a 3D Sleeper Slab object is placed following the vertical profile elevation, a 2D sleeper slab footing layout (decoration) is placed at elevation 0 in the model. This 2D layout is updated whenever the sleeper slab object is changed, and the line work has the necessary features associated to place it on a separate Level.
