Cruciform (topic)

Cruciform wf-wt material is composed of a wide flange section and wt sections. Like other cruciform shapes, it is defined in the local shape file . In the Auto Standard Connections setup window, cruciform is referred to as cruciform column -- for example, " WFlg Beam to Crux Col perp ." The material window for wf-wt cruciform material is the Rolled Section Material window.

Cruciform wf-pl material is composed of a wide flange section and rectangular plates. The material window for the wide flange is the Rolled Section Material window. The material window for the plate material is the Rectangular Plate Material window.

Cruciform pl-wt material is composed of wide flange sections and rectangular plates. The material window for the plate material is the Rectangular Plate Material window. The material window for the W tee material is the Rolled Section Material window.

Cruciform pl material is composed of rectangular plates. The material window for plates is the Rectangular Plate Material window.

Shape file specifications for cruciform wf-wt :

wf = wide flange section size
wt1 = NS tee section size
wt2 = FS tee section size

  • Weld specifications: " NS tee weld type " and " NS tee weld size " are for welding the web of the near side W tee section to the web of the wide flange section on its near side. " FS tee weld type " and " FS tee weld size " are for welding the web of the far side W tee section to the web of the wide flange section on its far side. Shape file weld specifications set the weld symbols for shop welds shown in the 3D model and for shop weld symbols on member details.
  • Other specifications: " Structural Properties " are material properties that can be edited in a full-featured SDS2 program .

Adding cruciform sections to the model (in a full-featured SDS2 program) :

  • Cruciform sections can be added to the model as the main material of a column by entering a cruciform " Section size " on a Column Edit window. Connection design can automatically create connections for cruciform columns .
  • A cruciform sections can also be the " Section size " that is entered for other member types. However, connection design is not supported for cruciform members other than columns.

Steel grades :

  • When the user of a full-featured SDS2 program specifies a cruciform " Section size " for a column, the " Steel grade " for that column is disabled ( grayed out ) since a cruciform section is a composite section composed of multiple materials which may or may not have different steel grades. Steel grades that will be applied to a selected section size come from Home > Project Settings > Job > Material Grades > Cruciform Grades .
  • On the Cruciform Grades window, users of a full featured SDS2 program can specify specific grades for the plates and/or W tees and/or wide flange materials that make up a cruciform section size.
