GGU-LATPILE: "Steel sections" menu item

If you want to design a steel pile to EC 3 via the section list, this menu item will open a dialog box containing the current list of steel sections.

Open

The following options are available:

• "Forw.", "Back", "Go to no."
  You can navigate through the list using "Forw." and "Back". "Go to no." allows you to jump to the section specified.

• "Cancel", "Done"
  Exit the dialog box either saving or rejecting your modifications using these buttons.

• "x Sections to edit", "Info"
  Using this button you may expand or reduce the list of steel sections. New sections are added to the end of the list. A description of the abbreviations used to enter the section data is available via the "Info" button.

• "Load", "Save", "Sort", "Delete doubles"
  A different section list can be opened by pressing the "Load" button. It is then possible to append the new list to an already open section list. After appending sections, it may be expedient to delete any double sections in the list by pressing the "Delete doubles" button. The sections can then be sorted either by moment of inertia or by name by pressing the "Sort" button. The modified section list may then be saved to the program folder as ".tbw_ggu" file for subsequent analyses by pressing the "Save" button.

• "Select section"
  A dialog box opens in which you select the required section for design.

Open

• "Simulate corrosion"
  You can define the corrosion for any sections, which is then used to calculate the new section data. The new section data can be allocated to the selected section, or to a different, existing section. The data can also be allocated to a new section, which is added to the existing list.

Open

• "Weld on plates"
  If you need to simulate reinforcement using weld-on plates, click the previous "Simulate corrosion" button and enter a negative corrosion.

• "Create tubular section"
  A new tubular section can be generated. A dialog box opens for entering the dimensions and identification. In the following dialog box, you can then save the section as a new section, or using a previously allocated name:

Open

• "Delete sections"
  Any number of sections in a sequence in the list can be deleted using this button.

Open

• "Create old record"
  Using this button you can save a record containing the old section tables based on the global safety factors (".tbw", ".spw").

If Steel design to EC 3 is not activated, the old dialog box opens. A check box in front of the number of each steel section can be activated. This is used to select the respective steel section. If you then press the "Selected section as design section" button, this section is used as the design section. The section parameters ("h" = height; "b" = width; "A" = area; "I" = moment of inertia) can be edited. The program uses I and h to determine the section modulus W during the subsequent design phase. The variable S is the first moment of area of the section and s is the web thickness. The value of "S/s" is required for verification of shear stress.
