Studs

Stud settings

• Height.

  Specifies a stud height.

• Stud diameter.

  Specifies a stud diameter.

• Single stud cost.

  Cost of each stud used in calculation of the beam cost and in cost optimization.

• Proportional Group Factor

  When enabled, it allows interpolation of group factors between code-supplied values when more than one row of studs is required only along part of a beam length.

• Use segmented studs (when available)

  Select this setting to use segmented stud distribution for girders, saved in Robot. See Design Assumptions - Studs. Segmented distributions are saved as a comma-delimited list, ordered from the start point of an analytical beam.

• Material

  Specifies steel used for studs, steel strength (Fu) and Young's modulus (Es). You can select:

  • Custom, for user-defined material. Then accept default or specify your values of Fu and Es.
  • Database material.
• Minimum and maximum spacing limits.

  Specifies the minimum and maximum allowable spacing for studs.

• Put Minimum studs on Non-Composite Beams.

  Select this option to add studs for the beam designed as non-composite (using the Design Non-Composite procedure).
