Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications, Including Supplement No.1

^{This supplement was developed by the AISC Connection Prequalification Review Panel (CPRP) using a consensus process. This document is the first supplement to ANSI/AISC 358-16, Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications. This supplement adds a new prequalified moment connection, the proprietary SlottedWeb Moment Connection, in a new Chapter 14. Chapter 11 covering the SidePlate Moment Connection has been expanded to include HSS columns and to permit bolted connections. Additionally, Chapter 10 covering the ConXtech CONXL Moment Connection has been revised to address a manufacturing safety issue. A nonmandatory Commentary has been prepared to provide background for the provisions of the Standard, and the user is encouraged to consult it. Additionally, nonmandatory User Notes are interspersed throughout the Standard to provide concise and practical guidance in the application of the provisions.}
