The Plate 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 ."
- Warning 2: 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.
- The steel grade entered to line 1 on this window is assigned by default to the first welded plate box or welded plate W member that is Added after starting up Modeling . If, on the member edit window, you enter a different steel grade, each subsequently Added plate member is assigned that steel grade until you change the steel grade again or restart Modeling .
- Line 1 applies to rectangular plate , round plate , bent plate or rolled plate added using Add Material in the same way that it applies to members.
- Submaterials that are generated during connection design use (by default) the " Plate material grade " that is selected in Home > Project Settings > Fabricator > Standard Fabricator Connections > Plates . User base/cap plates use the " Steel Grade " set in the Base / Cap Plate Schedule .
- Cut ( Ctrl + x ), copy ( Ctrl + c ) and paste ( Ctrl + v ) are available to 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 warning 2 .

Step-by-step instructions :
1 . To open the Plate Grades window, use one (1) of the following methods:
Method 1 : Home > Project Settings > Job > Material Grades > Plate Grades .
Method 2 : In Modeling or the Drawing Editor , choose Settings > Job Settings > Plate Grades (classic), or use a keyboard shortcut , or click the icon.
2 . The Plate 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 " " Ry " " Rt " |
shown when ' ASD13 ' or ' LRFD13 ' or ' CISC8 ' or ' CISC9 ' or ' ASD9 ' or ' LRFD3 ' or ' ASD1 ' 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 ." |
Please note: Changes to the " ASD/LRFD/CISC " tab are automatically copied to the " ASD/LRFD/CISC " tab of the Flat Bar Grades and Round and Square Bar Grades windows.
3 . See Warning 1 and Warning 2 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 Warning 2 . 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.
Do not change the entry to line 1 (or, for that matter, any other line) when your current Job is under development. Doing so may result in materials in your current Job being reassigned different steel grades. Steel Grade: Any text string (up to 29 characters) to denote the name of the steel grade (e.g., A36 , A401 , Peter , Joe , whatever name you want). Steel grades entered here are selectable (
) in Modeling wherever a plate section is entered as the " Section size ." Default steel grades for various connection plates that are generated during connection design are entered in Home > Project Settings > Fabricator > Standard Fabricator Connections > Plates . You can also select these steel grades on the Rectangular Plate Material , Round Plate Material , Bent Plate Material , Rolled Plate Material , Flat Bar Mtrl (except for AS4100), Round Bar Mtrl (except for AS4100), or Square Bar Mtrl (except for AS4100), or Multi-Sided Flat Plate Material windows.
Nonstandard Notation: Any text string (up to 29 characters) to denote that a particular steel grade used is not the standard steel grade.
For member main material: This " Nonstandard Notation " string may be made to appear as a part of the section size of welded plate members. In a Modeling erection view, the notation appears when " Section sizes " are shown and the " Denote non-standard material " setup option is turned on. To get the annotation on an erection view drawing, you need to check the box for " Denote non-standard material " when you auto detail the erection view. Example 1: Enter * as the " Nonstandard Notation " for all lines but the first line if you wanted section sizes for welded plate main materials with nonstandard plate steel grades to be marked with a * . Example 2: (A588) for A588 steel if you want (A588) to be displayed in the model next to the member's section size when ' A588 ' is selected ( ) as the member's " 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 particular steel grade based on the thickness of the plate material.
Fy: The yield strength of the particular 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 in megapascals (MPa). The value you enter for Fy is used to design connections.
Fu: The ultimate strength of the particular 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). The value you enter for Fu is used to design connections.
Ry (" ASD/LRFD "): The ratio (no units) of expected yield stress to the specified minimum yield stress, Fy. See section I-6 of the AISC Seismic Design Manual . This overstrength factor is used during connection design for calculations related to member strength when the user has specified a " Seismic brace " (vertical brace). The default values used for " Ry " come from Table I -6 -1 of the AISC Seismic Design Manual . " Ry " is used only when the governing load (" Tension load " or " Compression load ") is "
Auto ." " Ry " and " Rt " are not used for user-entered loads.
Rt (" ASD/LRFD "): The ratio (no units) of the expected tensile strength to the specified minimum tensile strength, Fu, as related to overstrength in material yield stress Ry. See section I-6 of the AISC Seismic Design Manual . This overstrength factor is used during connection design when the user has specified a " Seismic brace ." The default values used for " Rt " come from Table I -6 -1 of the AISC Seismic Design Manual . " Rt " is used only when the governing load (" Tension load " or " Compression load ") is "
Auto ." " Ry " and " Rt " are not used for user-entered loads.
Correlation Factor (" Eurocode "): 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.
