Steel Seismic Provisions Technical Notes

Seismic code-check capabilities are available for steel members and moment frame joints. The seismic provision checks include checking the member design and detailing requirements against the requirements of the selected seismic code.

Note: For CAN/CSA S16-01 and S16-09, the Seismic Design Requirements of Chapter 27 have not been implemented.

Steel Design Codes

The seismic steel post-processors are based on the requirements of the code specifications published by:

The International Conference of Building Officials (ICBO) as found in the 1997 Uniform Building Code, Volume 2,
American Institute of Steel Construction as found in Seismic Provisions for Structural Steel Buildings.

These specifications include:

American Institute of Steel Construction, Inc. – Seismic Provisions for Structural Steel Buildings (2016, ANSI/AISC 341-16, July 12, 2016)
American Institute of Steel Construction, Inc. – Seismic Provisions for Structural Steel Buildings (2010, ANSI/AISC 341-10, June 22, 2010)
American Institute of Steel Construction, Inc. – Seismic Provisions for Structural Steel Buildings (2005, ANSI/AISC 341-05, March 9, 2005, including supplement No.1 Dated November 16, 2005)
American Institute of Steel Construction, Inc. – Seismic Provisions for Structural Steel Buildings (2002, ANSI 341-02, May 21, 2002)
American Institute of Steel Construction, Inc. – Seismic Provisions for Structural Steel Buildings (April 15, 1997)
Uniform Building Code 1997 – Section 2212, Seismic Provisions for Structural Steel Buildings – Allowable Stress Design and Plastic Design.
Uniform Building Code 1997 – Section 2210, Seismic Provisions for Structural Steel Buildings – Load and Resistance Factor Design Specifications for Structural Steel Buildings.

The requirements of the latest Supplement to the AISC 341-05 requirements have been implemented:

AISC Seismic Provisions for Structural Steel Buildings. Supplement No.1. (November 16, 2005).

The requirements of the latest Supplement to the AISC 1997 requirements have been implemented:

AISC Seismic Provisions for Structural Steel Buildings (1997) Supplement No.2. (February 1999).

The requirements of the latest Federal Emergency Management Agency Guidelines have been implemented for UBC 1997 LRFD and AISC 1997:

FEMA 350, Recommended Seismic Criteria for New Steel Moment-Frame Buildings, (July 2000), including June 18, 2001 errata.

When selected by the user the provisions from this code can be checked in lieu of the equivalent UBC 97 or AISC 1997 provisions.
