Seismic design rules (Columns: AISC 360)

Additional design rules are required for seismic combinations. These are as per the AISC Seismic Provisions (AISC 341-05) (Ref. 5). These additional design rules ONLY apply to members in Seismic Load Resisting Systems.

The rules applied depend upon the seismic load resisting system as defined in the AISC Seismic Provisions and are listed below:

For a moment resisting frame

9. Special Moment Frame (SMF)

  • 9.4a. Classification
  • 9.4. Column strength check
  • 9.6. Column/beam moment ratio

10. Intermediate Moment Frame (IMF) • 10.4a. Classification

  • 10.4. Column strength

11. Ordinary Moment Frame (OMF)

  • 11.4. Classification
  • 11.4. Column strength check

Moment resisting frame with a truss component

12. Special Truss Moment Frame (STMF) 1- Beyond Scope

For a braced frame

13. Special Concentrically Braced Frames (SCBF)

  • 13.2d. Classification
  • 13.2b. Column strength check

14. Ordinary Concentrically Braced Frames (OCBF)

  • 14.2. Classification
  • 14.2. Column strength check

15. Eccentrically Braced Frames (EBF) - Beyond Scope

Buckling resistant braced frame

16. Buckling Restrained Braced Frames (BRBF) - Beyond Scope

Frames containing composite beams

Composite Special Concentrically Braced Frames (C-SCBF) - Beyond Scope

Composite Ordinary Braced Frames (C-OBF) - Beyond Scope

Composite Eccentrically Braced Frames (C-EBF) - Beyond Scope
