OpenBridge Modeler

To place the segments at abutments

To place the balanced cantilever segments at the abutments, do the following.

In a typical balanced cantilever construction, the abutment cantilevers are placed first. While in the OpenBridge Modeler model, this doesn't have any direct impact, numbering the order that the builds are placed is exported to analysis and design software such as RM Bridge, uses this data for staged construction analysis.
  1. On the Home ribbon tab, select the Place Segmental > Place tool in the Superstructure group


  2. In the Place Cantilever Segmental tool settings dialog, select the segment template to use:
    1. Click […] adjacent to the Template Name setting. The Template Selection dialog opens.
    2. In the Standard Templates list, select the SegBox0600 template.
    3. Click OK.
  3. Set the following tool parameters:
    1. Check the Build Order option and type a value of 1.
    2. Check the Seg. Length option and type a value of 5@9 (m).
    3. Check the Pier Seg. Length option and type a value of 5 (m).
    4. Select Segment for the Feature Definition.
    Leave the other fields their default (offsets and CIP Length of 0.0000, chorded option clear, Constraints option clear, and Template Orientation of vertical).
    Note: You will add constraints for the overall depth variation once all segments are placed.
  4. Data point on the first supportline. The length back and ahead are displayed (UB and UA) for the preliminary placement are displayed.
  5. Repeat step 4 to place the same cantilever segments on supportline 4.
    Tip: The Build Order will automatically increment to 2.
