2010 AISC Prequalified Seismic Moment Connection Standard Available as a Free Download

September 16, 2011 from American Institute of Steel Construction

(Chicago, IL) - The 2010 AISC standard, Prequalified Moment Connections for Special and Intermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358-10) is now available for free downloading on the AISC web site at www.aisc.org/aisc358. Released concurrently with a fully integrated supplement, the new standard now covers six connections: reduced beam section moment connections; bolted stiffened and unstiffened extended end-plate moment connections; bolted flange plate moment connections; welded unreinforced flange-welded web moment connections; Kaiser bolted bracket moment connections; and ConXtech CONXL moment connections. In addition to general requirements and limitations, each prequalified connection chapter includes a step-by-step design procedure.

The new standard has been approved by the AISC Connection Prequalification Review Panel (CPRP) and is ANSI-accredited. “The committee is pleased to be able to provide designers with more resources for seismic design,” said Ronald O. Hamburger, Chairman of the Committee. “Additional connections are already in the prequalification process, so our list of connections should continue to grow.” ANSI/AISC 358 is an essential companion to the AISC Seismic Provisions (ANSI/AISC 341-10), which outline the requirements for the prequalification of seismic moment connections in Chapter K.

ANSI/AISC 358-10 and its integrated supplement, ANSI/AISC 358s1-11, are available as a single free download at www.aisc.org/aisc358. Learn more about the standard, as well as other current AISC specifications and codes available for free downloading, at www.aisc.org/specifications.
