To define a steel rolled shape beam

To add a beam definition for a slab with steel girder bridge that uses a rolled shape, use the following procedure.

You must have previously created a beam layout and placed a beam group.
Once the Beam Definition dialog is open for a slab on steel girder bridge, you can define rolled shape steel beams.
  1. Select a beam in the Beams list.
  2. Select Rolled Shapes from the Beam Sections drop-down.
  3. (Optional) Type a Beam Minimum Haunch height.
    Note: You can uncheck this option for steel girders if a minimum haunch is not necessary.
  4. (Optional) You can create a beam splice within a span to vary the rolled shape or material:
    1. Click Insert Row After (). A new row is added to the table.
    2. Type the Distance or Ratio value. The other value will be automatically populated based on the selected beam's span.
    3. Select Head or Tail in the From cell drop-down to indicate where the distance or ratio is taken from.
    4. Select either Distance or Ratio in the Lock To cell drop-down to indicate which value to use.
  5. For the beam or beam segments, select the Template and Material from the respective cell drop-downs.
  6. Either:

    select a different beam in the Beams list to define it

    or

    copy a beam definition to other beams

  7. Once you have defined all the beams in the layout, click OK.
The Beam Definition dialog closes and the beams are added to the model.
