The Turnbuckle / Clevis / Pin Grades window ( Job Settings )

Shown here are the columns you get for the " ASD/ LRFD/ CISC " tab. You will get additional columns if the " AS4100 " or " Eurocode " tab is shown. Which of these tabs is shown depends on the selected " Connection design method ."
  • The Turnbuckle / Clevis / Pin Grades window lets you define a new steel grade so that you can assign it as the " Steel grade " to a turnbuckle, clevis or pin. You can also use it to edit existing steel grades.
  • Warning: Changing any steel grade definition (for example, changing line 3) assigns the new definition to all materials that had been assigned the previous definition. Since a steel grade is assigned to a material by its line number (index), this means that if you switch line 3 with line 4, the steel grades of existing materials using those definitions will also be switched.
  • If you want connection design to create a rod brace, you can enter round bar material as a vertical brace " Section size ." The two (or three) round bars will be assigned the " Steel grade " specified on the Vertical Brace Edit window. The rod brace's top and bottom clevises, turnbuckle(s) and clevis pins are assigned the steel grade entered to line 1 on this window.
  • The Fy and Fu values on this window are used by connection design of rod bracing for evaluating the strength of a clevis pin of a particular " Clevis pin grade " (bottom clevis) or " Clevis pin grade " (top clevis). The " Capacity " (nominal strength) of a clevis and turnbuckle used in a rod brace is stored in the local shape file.
  • Cut ( Ctrl + x ), copy ( Ctrl + c ) and paste ( Ctrl + v ) can help you more quickly edit steel grades. You can also choose " Cut " " Copy " or " Paste " on the context menu that opens when you right-click a cell. See the warning .

Step-by-step instructions :

1 . To open the Turnbuckle / Clevis / Pin Grades window, use any one (1) of the following methods:

Method 1 : Home > Project Settings > Job > Material Grades > Turnbuckle / Clevis / Pin Grades .

Methods 2, 3 & 4 : In Modeling or the Drawing Editor , choose Settings > Job Settings > Turnbuckle / Clevis / Pin Grades (classic), or use a keyboard shortcut , or click the icon.

2 . The Turnbuckle / Clevis / Pin Grades window opens. Which tab is shown on the window depends on the " Connection design method " that you are using. For example, the " ASD/LRFD/CISC " tab is shown when ' LRFD13 ' is the " Connection design method ."

Tab Columns When Shown  
" ASD/LRFD/CISC "  
" Line number " " Steel Grade " " Nonstandard Notation " " Fy " " Fu " 		shown when ' ASD13 ' or ' LRFD13 ' or ' CISC8 ' or ' CISC9 ' or ' ASD9 ' or ' LRFD3 ' or ' ASD14 ' or ' LRFD14 ' or ' CISC10 ' is the " Connection design method ."
" AS4100 " " Line number " " Steel Grade " " Nonstandard Notation " " Fy " " Fu " " Minimum Thickness " " Maximum Thickness " shown when ' AS 4100 ' is the " Connection design method ."
" Eurocode " " Line number " " Steel Grade " " Nonstandard Notation " " Fy " " Fu " " Minimum Thickness " " Maximum Thickness " " Correlation Factor " shown when ' EUROCODE3 ' or ' EUROCODE3 UK ' is the " Connection design method ."

3 . See the warning before making any changes to this window. To add a new steel grade, fill out the columns for the first blank line (press the Tab key or Shift + Tab to move from cell to cell). The type of information that may be entered beneath a particular column on this window is explained below:

Line number: The index number (a positive integer) of the steel grade -- see the warning . Line 1 sets the default steel grade and is the standard steel grade that may be referenced when Home > Project Settings > Fabricator > Member and Material Piecemarking > the " Submaterial " tab > " Show non-std grade notation with piecemarks on member details " is checked.

Steel Grade: Any text string (up to 29 characters) to denote the name of the steel grade (e.g., A108 , A493 , Peter , Joe , whatever name you want). Steel grades entered here are selectable ( ) as the " Clevis pin grade " (a connection design lock for rod braces), the " Steel grade " for turnbuckle material, and the " Clevis grade " for clevis material.

Nonstandard Notation: Any text string (up to 29 characters) to denote that a particular steel grade is not the standard steel grade.

For submaterials: A callout is generated next to that material's submaterial piecemark callout on the member detail when Home > Project Settings > Fabricator > Member and Material Piecemarking > the " Submaterial " tab > " Show non-std grade notation with piecemarks on member details " is checked. The callout will consist of the steel grade if you do not enter a " Nonstandard Notation ." If, on the other hand, a " Nonstandard Notation " has been entered, that notation would be called out instead of the steel grade. For example, you might enter Non Std as a " Nonstandard Notation ."

Minimum Thickness & Maximum Thickness (" AS4100 " and " Eurocode "): These columns let you assign Fy (yield strength) and Fu (ultimate strength) values to a steel grade based on the diameter of the pin.

Fy: The yield strength of the steel grade. If you are using imperial dimensioning, yield strength is measured in kips/sq. inch (ksi). If you are using metric dimensioning, yield strength is measured in megapascals (MPa) Connection design evaluates Fy and Fu values for clevis pins only. Clevis and turnbuckle strengths come from the item's " Capacity " in Shapes Properties . Connection design locks are available for setting the " Clevis pin grade " (bottom clevis) and " Clevis pin grade " (top clevis) on a rod brace.

Fu: The ultimate strength of the steel grade. If you are using imperial dimensioning, ultimate strength is measured in kips/sq. inch (ksi). If you are using metric dimensioning, ultimate strength is in megapascals (MPa). Connection design evaluates Fy and Fu values for clevis pins only. Clevis and turnbuckle strengths come from the item's " Capacity " in Shapes Properties . Connection design locks are available for setting the " Clevis pin grade " (bottom clevis) and " Clevis pin grade " (top clevis) on a rod brace.

Correlation Factor (" Eurocode " tab) : The appropriate correlation factor (ß w ) taken from Table 4.1 in BS EN 1993-1-8: 2005, " Eurocode 3: Design of steel structures ." The factor is used in calculations for fillet welds.

4 . When you are done making changes to the Turnbuckle / Clevis / Pin Grades window, use the buttons at the bottom of this window to reorder listings on the window or close the window or undo your changes.

       

"Move Up" or "Move Down" change the order of items on the window. Warning!! If you move a steel grade to a line number whose steel grade has already been assigned to materials in your current Job, when you press " OK " those materials are assigned the newly moved steel grade -- see the Warning .

"OK" (or the Enter key) closes the window and saves the settings on it to the Job Settings file in your current Job .

"Cancel" (or the Esc key or the button) closes the window without saving any changes.

"Reset" undoes all changes made to this window since you first opened it. The window remains open.
