Shear and Threaded Stud Grades

The Shear and Threaded Stud Grades screen lets you define a new grade so that you can assign it as the Grade to a shear stud or threaded stud, or to edit existing grades. These settings are stored for your currently selected Connection design method.
  • General Overview
  • Tips and Tricks
  • Related Tools
The columns shown here are for the latest AISC Connection design method. Additional columns may be shown if another Connection design method is selected.

To add a new Grade Type or Grade, right-click inside the table and select Add Grade Type or Add Grade.
  • Warning: When you change a grade definition, all materials that used the previous definition automatically adopt the new grade. Because grades are linked to materials by their index, switching the 3rd and 4th grades in the table will also swap the grades of all existing materials that use them.

Available Settings by Design Method

Screen Columns When Shown
ASD/LRFD/CISC Grade Type, Grade, Nonstandard Notation, Fy, Fu, Density shown when an ASD, LRFD, or CISC Connection design method is selected.
AS4100 Grade Type, Grade, Nonstandard Notation, Fy, Fu, Minimum Thickness, Maximum Thickness, Density shown when AS 4100 is the Connection design method.
Eurocode Grade Type, Grade, Nonstandard Notation, Fy, Fu, Minimum Thickness, Maximum Thickness, Correlation Factor, Density shown when EUROCODE3 or EUROCODE3 UK is the Connection design method.

Settings

Grade Type: Any text string (up to 29 characters) to denote the name of the grade type (e.g., Steel, Stainless, Aluminum).

Grade: Any text string (up to 29 characters) to denote the name of the grade (e.g., A108, A493, Peter, Joe, whatever name you want). Grades entered here are selectable ( ) as the Grade for shear studs or threaded studs in Modeling.

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

For submaterials: A callout is generated next to that material's submaterial piecemark callout on the member detail when Home > Project Settings > Fabricator > Piecemarking > Member and Material Piecemarking > Submaterial > Show non-std grade notation with piecemarks on member details is checked. The callout will consist of the 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 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 grade based on the diameter of the stud material.

Fy: The yield strength of the 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). Since connection design does not evaluate Fy and Fu values for shear studs or threaded studs, this value is for your reference only.

Fu: The ultimate strength of the 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). Since connection design does not evaluate Fy and Fu values for shear studs or threaded studs, this value is for your reference only.

Density: The density value of the grade. If you are using imperial dimensioning, density is measured in lb/ft3. If you are using metric dimensioning, density is measured in kg/m3. The value you enter for density is used to calculate material weight.

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.
