S tee material (topic)

Tip: Connection design can create connections for S tee horizontal and vertical braces in generally the same framing situations that it can design connections for W tee braces. However, bolting an S tee brace is more difficult than to W tee brace because of the angular surface inside its flange. At left is a cross section of an ST9x35.

General description :

  • S tee material is rolled steel with a cross section that is "T" shaped. It is basically a S shape section that has been cut in half. It has a top flange and a web (the "stem").
  • S tee material is a type of "tee material."

Entering S tee section sizes :

  • Naming convention: ST+nominal_depth+x+nominal_weight/length .
  • Example: ST9x35 .
  • Note: When you add an S tee to a shape file, you do not have to follow this naming convention.
  • In Modeling and the Drawing Editor : An S tee section must exist in the local shape file before you can enter it as a " Section size " to a member or material edit window, or before its weight can be automatically calculated when you add it to the " Description " field in the bill editor.

Adding S tee sections to the model :

  • To add an S tee to a member as a submaterial (pre-selection method): Select the one (1) member that you want to add the material to (so that it is displayed in the " Primary selection color ") > press F3 > filter for " Hot / Cold Rolled " > double-click " Rolled Section " > locate two material work points > enter an S tee " Section size " on the Rolled Section Material window > optionally rotate the material into place > locate a material dimension reference point > right-click ( Return ) if done adding material to the member > Change All Options can be applied if the material is being added to a member that is batched together with other members that have the same member piecemark.
  • To add an S tee as a miscellaneous member: Press F2 > filter for " Miscellaneous steel " > double-click " Rolled Section " > locate two member work points > enter an S tee " Section size " on the Rolled Section Edit window > right-click ( Return ) if you are done adding duplicates or variations of the miscellaneous member.
  • To add an S tee as a legacy miscellaneous member, click here for instructions.
  • Locating work points for an S tee that is added as material or a legacy miscellaneous member should be done in a view whose work plane is orthogonal to (at right angles to) the material being added. A rolled section miscellaneous member , on the other hand, can be added and properly rotated into place even in an isometric view.
  • Settings for S tees added as legacy miscellaneous members or submaterial may be entered on the Rolled Section Material window. Settings for S tee miscellaneous members may be entered on the Rolled Section Edit window. Additional settings can be found in the local shape file (see above ).
  • Connection design does not ever use S tee sections in connection design since a comparable W tee section is almost always a better choice.
  • S tee sections can also be added to the model as the main material of a member by entering the appropriate " Section size " (example: ST3x6 ) on a member edit window. Connection design can automatically generate connections for S tee vertical braces and S tee horizontal braces .
