The 2016 version of the American Institute of Steel Construction (AISC) standard, Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358-16) is now available for free downloading on the AISC website at www.aisc.org/aisc358.Â
This updated version has been expanded to cover nine connections:Â
• Reduced beam section moment connectionsÂ
• Bolted stiffened and unstiffened extended end-plate moment connectionsÂ
• Bolted flange plate moment connectionsÂ
• Welded unreinforced flange-welded web moment connectionsÂ
• Kaiser bolted bracket moment connectionsÂ
• ConXtech ConXL moment connectionsÂ
• SidePlate moment connectionsÂ
• Simpson Strong-Tie Strong Frame moment connectionsÂ
• Double-tee moment connectionsÂ
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.Â
“With the release of AISC 358-16, there are now nine prequalified beam-to-column moment connections for Special and Intermediate Moment Frames,” said Michael D. Engelhardt, chairman of the committee. “Work is already underway to prequalify additional connections and to extend the range of use for some of the existing prequalified connections, with the goal of providing designers with an ever growing range of options.”

EPA Says Additional Lead Paint Cleaning Rules Not Necessary
The EPA has concluded that current Lead: Renovation, Repair, and Painting Program (LRRP) cleaning requirements and lead-safe work regulations are sufficient to protect the public from lead dust hazards. “Our members have been instrumental in contacting legislators to detail the detrimental impact of the current LRRP," says Richard Walker, American Architectural Manufacturers Association’s president and CEO. “This collective industry voice has prompted the EPA to make the responsible decision to refrain from adding further, unnecessary costs to homeowners under the current economic climate."http://www.aamanet.org/news/1/10/0/all/603/aama-commends-its-members-congress-for-vacating-lrrp-clearance-rule
