This live web event has ended. Thank you for attending.


Moment connections play a vital role for the intended performance of steel Special or Intermediate Moment Frames in a seismic event. The lessons learned from the 1994 Northridge Earthquake drastically changed the way that moment connections are designed. This presentation will provide a historic account of the development that led to the current design and construction practice as required in AISC 341 and AISC 358. The number of prequalified connections contained in AISC 358 was increased from two in its 2005 edition to ten in the current edition. The prequalification process, limitations, and general design process contained in this standard will also be highlighted.

  • Course will award 1.5 hours of continuing education
  • This course is Diamond Review approved in 49 states. New York does not accept hours from recordings.
Please note: This webinar is part of the Seismic Connections Series and is not included in the NCSEA Webinar Subscription. The registration fee for the Series is $595 for members ($900 for nonmembers), which includes all 9 hours of education.
