The 2010 AISC Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-10) is now available as a free download on AISC’s web site at www.aisc.org/2010SP. This new specification supersedes the 2005 AISC Seismic Provisions for Structural Steel Buildings and all previous versions of this specification. It has been approved by the AISC Committee on Specifications and is ANSI-accredited. The 2010 Seismic Provisions have also been adopted by reference in the 2012 International Building Code, and as a result will soon govern the seismic design of all steel buildings in the United States.
As in the past, the 2010 Seismic Provisions was written as a supplement to the current AISC Specification for Structural Steel Buildings (ANSI/AISC 360-10), providing design requirements for seismic force resisting systems. The most obvious revision to the new Seismic Provisions is the new chapter format which resembles the AISC Specification. Additionally, the incorporation of Part II, Composite Structural Steel and Reinforced Concrete Buildings, with Part I, Structural Steel Buildings, is a notable formatting change that will clarify the design of composite systems. Other revisions and updates in the 2010 Seismic Provisions include:
- Establishing a new chapter on analysis requirements that applies to all systems
- A discussion on the “Basis of Design” that explains the intended seismic response characteristics of each structural system
- Adding requirements for two cantilever column systems to be consistent with other systems in these provisions and the definitions in ASCE/SEI 7-10
- Adding analysis requirements to address the inelastic response of special concentrically braced frames
A list of additional revisions and updates can be found in the Preface of the document.
