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

Shown here are the settings you get for the " ASD/ LRFD/ CISC " tab. You will get additional settings if the " AS4100 " or " Eurocode " tab is shown. Which of these tabs is shown depends on the selected " Connection design method ."
  • To open this window
  • Defaults for rod bracing:

    • Rod braces are created by connection design when the user of a full-featured SDS2 program enters round bar material as a vertical brace " Section size ." The two (or three) round bars is assigned the " Steel grade " specified on the Vertical Brace window. The rod brace's top and bottom clevises, turnbuckle(s) and clevis pins will be 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. The " Capacity " (nominal strength) of a clevis and turnbuckle used in a rod brace is stored in the local shape file.

Tabs and columns on the window :

Tabs: ASD/LRFD/CISC or AS4100 or Eurocode . Which tab applies to your current Job depends on the " Connection design method " that is selected for that Job.

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 ."

Line number: The index number that a full-featured SDS2 program assigns the steel grade. Line 1 sets the default steel grade.

Steel Grade: Any 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 ( ) by users of this Job in a full-featured SDS2 program wherever a steel grade can be specified for turnbuckles, clevises and clevis pins. For example, on the Clevis Material window or in the Brace Connection To Gusset connection design locks for rod braces.

Nonstandard Notation: Any 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 " Show non-std grade notation with piecemarks on member details " is checked in Member and Material Piecemarking (setup) and an affected member detail undergoes automatic detailing in a full-featured SDS2 program .

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 shape file. A connection design lock for " Clevis pin grade " can be found in the Brace Connection To Gusset leaf.

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 shape file. A connection design lock for " Clevis pin grade " can be found in the Brace Connection To Gusset leaf.

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.
