M.To create a wide-flange user table section

To create a user-provided table section with a wide flange profile, including those with composite flanges or additional bottom plates, use the following procedure.

You may want to change the input dimensions prior to creating user provided table sections. Select Tools > Set Current Input Unit to do so.

  1. On the Specification ribbon tab, select the User Table > User Table Manager tool in the Beam Profiles group.

    If no User Defined Table exists, you will be prompted to create one.

    The User Table Manager dialog opens.
  2. Click New Table. The New User Table dialog opens.
  3. the Select Section Type list, select WIDE FALNGE and then click OK. The dialog closes and the Table Data list in the User Table Manager dialog now has at least one entry.
  4. Click Add.

    The Wide Flange dialog opens.

  5. Type a Section Name.
  6. Required: Enter the following wide flange section parameters:
    D
    Depth of the section
    TF
    Thickness of top flange (or both flanges when WF1 is not specified)
    WF
    Width of the top flange (or both flanges when WF1 is not specified)
    TW
    Thickness of web

    Wide flange section

  7. (Optional) If the bottom flange has different dimensions, also specify:
    WF1
    (Optional) Width of the bottom flange. The width of the top flange will be used if this value is not specified.
    TF1
    (Optional) Thickness of bottom flange. The thickness of the top flange will be used if this value is not specified.
  8. (Optional) To specify a composite top flange:
    1. Check the Additional Composite Flange option. The Additional Composite Flange Specifications become active.
    2. Specify the following values:
      B(left)
      Width of the composite slab to the left of the web center line
      B(right)
      Thickness of the composite slab
      Thickness
      Width of the composite slab to the right of the web center line
      Modular Ratio
      Modular ratio of the concrete in the composite slab with respect to the steel section material
  9. (Optional) To specify an additional bottom flange plate:
    1. Check the Additional Bottom Steel Plate option. The Additional Bottom Steel Plate Specifications become active.
    2. Specify the following values:
      B(left)
      Width of the additional bottom flange plate to the left of the web center line
      B(right)
      Width of the additional bottom flange plate to the right of the web center line
      Thickness
      Thickness of the additional bottom flange plate
  10. Specify the section properties by either:
    Option Description
    To automatically have the program calculate the section properties… Click Calculate.

    The program calculates the Ax, Iz, Iy, Ix, Ay, Az values from the provided section dimensions.

    To manually specify the section properties… Type values for:
    • Cross Section Area (Ax),
    • Inertia about local z (Iz),
    • Inertia about local y (Iy),
    • Torsional Constant (Ix),
    • Shear Area in Y (Ay), and
    • Shear Area in Z (Az)
  11. Click OK.
  12. (Optional) Repeat steps 4 through 11 to add more wide flange sections.
    Tip: The wide flange sections in the same user table can have different options for composite flanges or additional bottom steel plates.
  13. Click Close.

The section can now be added for use in the Properties - Whole Structure dialog by selecting it in the User Property Table dialog.

Refer to EX. US-17 User-Provided Tables and EX. UK-17 User-Provided Tables for examples of wide flange user-provided tables.
