M. To assign cracked section properties to a member

To assign reduced section property factors to a member, use the following procedure.

Global reduction factors will be applied to any member, regardless of material. Code-specific reduction factors are only applied to concrete members (non-concrete members included in the assignment are ignored).

  1. Optional: Select the members which will all have the same member specification assigned.
  2. On the Specification ribbon tab, select the Beam > Cracked Property tool in the Specification group.

    The Member Specification dialog opens to the Property Reduction Factors tab.
  3. Select either:
    • Global – specify the Reduction Factors to be used below, which will apply to any member regardless of material.
    • Code Specific – select the building code to use reduction factors specific to load cases per that code which are only applied to concrete members:
      • IS1893 2016
  4. Type the reduction factor values to assign to the current member selection:
    • Reduction Factor for Cross sectional Area (RAX)
    • Reduction Factor for Torsion Constant (RIX)
    • Reduction Factor for Moment of Inertia, major axis (RIY)
    • Reduction Factor for Moment of Inertia, minor axis (RIZ)
  5. Either:
    To…Do the following…
    add the specification to the model and assign to the current member selection click Assign.
    add the specification to the model for later assignment click Add.
