Prequalified Moment Connection Standard Supplement Now Available for Public Review
Posted by MSC on October 13, 2008 at 3:54 PM.

Supplement No. 1 to the 2005 AISC Standard Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358-05) is now available for a second public review. This supplement includes limited revisions to existing provisions for End-Plate and Reduced Beam Section (RBS) Connections, and provides design provisions for additional moment connection technologies, including the Bolted Flange Plate (BFP) Moment Connection, the Welded Unreinforced Flange–welded Web (WUF-W) Moment Connection, and the Kaiser Bolted Bracket (KBB) Proprietary Cast Moment Connection. The Supplement also includes an appendix for cast steel material and quality.

 

The only item to be reviewed in this ballot is Section A.2.4(2)b. The proposed revision increases the sampling to 50% of the production castings from 25% in the previous ballot. This change was made as a result of negative comments received on the first ballot and the committee’s determination that this rate would be more consistent with that necessary to assure a quality product.

 

The complete supplement is available for your review by downloading the document at the links provided below. A hard copy of the supplement can also be requested for a fee of $15 by e-mail to cummins@aisc.org.
