Shown here are the columns you get for the " ASD/ LRFD/ CSA " 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 Plate Grades window lets you add a new steel grade for plate material, or to revise an existing plate material steel grade. Please heed the warnings.
- Warning 1: Use caution when changing the Fu and Fy values assigned to particular steel grades. The Fu and Fy values assigned to steel grades in the default Job Settings file are the correct ultimate strength and yield strength values for those grades. Changing Fu and Fy values affects connection design .
- 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 .

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/CSA " tab is shown when ' LRFD13 ' is the " Connection design method ."
|" ASD/LRFD/CSA "||
" Line number " " Steel Grade " " Nonstandard Notation " " Fy " " Fu " " Ry " " Rt "
|shown when ' ASD13 ' or ' LRFD13 ' or ' CSA8 ' or ' CSA9 ' or ' ASD9 ' or ' LRFD3 ' or ' ASD1 ' or ' LRFD14 ' or ' CSA10 ' 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/CSA " tab are automatically copied to the " ASD/LRFD/CSA " 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.
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.
"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 Warning 2 .
"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 originally opened it. The window remains open.
