摘要

The 1994 Northridge earthquake resulted in an unprecedented level of interest in the seismic performance of steel frame structures. This interest led to major research and development programs sponsored by the Federal Emergency Management Agency (FEMA) and others, including the FEMA/SAC Steel Program. As a result of these efforts, significant modifications to the United States seismic design provisions for steel structures have taken place. The AISC Seismic Provisions for Structural Steel Buildings, hereafter referred to as the AISC Seismic Provisions, were almost completely rewritten in 1997, with additional major modifications in 1999 and late in 2000. The 2002 AISC Seismic Provisions are the basis for the steel seismic design provisions in the 2002 National Fire Protection Association (NFPA) 5000 and the 2003 International Building Code (IBC). The 2002 AISC Seismic Provisions incorporate information from the final FEMA/SAC recommendations presented in FEMA 350 through 355. The contents of the previous editions of the AISC Seismic Provisions will be briefly summarized in this paper. The paper will focus on the 2005 AISC Seismic Provisions that are referenced in the 2006 IBC. In addition to updating the requirements for systems used in current design practice to be consistent with recent research results, these provisions also have incorporated two new systems that can be used for various applications (steel plate shear walls and buckling restrained braced frames). The 2005 AISC Seismic Provisions (AISC, 2005b) have been developed so that the main AISC Specification for Structural Steel Buildings (AISC, 2005a) (also completed in 2005) can be used as a primary reference.
