ABSTRACT
The 1997 American Institute of Steel Construction (AISC) document “Seismic Provisions for Structural Steel Buildings,” are becoming the reference document for seismic design of steel structures throughout the United States. The 2000 International Building Code has incorporated these provisions by reference, and it is expected that the 2002 National Fire Protection Association 5000 Building Code and the 2003 International Building Code will also follow this approach. Since their 1997 publication, the AISC Seismic Provisions have been updated on a regular basis in order to incorporate new developments from the FEMA/SAC project on moment frames and other work in this area. To date, two such supplements have been produced and published by AISC, the first early in 1999 and the second late in 2000. The next revision, which will culminate with the publication of a completely new set of provisions, is presently being completed by AISC. Publication will occur during 2002. This revision will continue to incorporate the findings of the recently completed FEMA/SAC steel project. In addition, it is expected that a number of additional modifications will be made to provide the latest available information to the design community. After publication of the 2002 AISC Seismic Provisions, efforts will continue to keep seismic design provisions as current as possible. Coordinated efforts between AISC and the Building Seismic Safety Council (BSSC) are intended to continue the process of keeping the seismic design provisions for structural steel buildings as current as possible. This presentation will summarize the changes to be incorporated into the upcoming edition of the AISC Seismic Provisions. It will also speculate on future modifications and additions to the U.S. seismic design provisions for structural steel buildings
