ANSI/AISC 358-16 Prequalified Connections for Special and Intermediate Steel Moment Frames

The prequalified connections standard has been developed by the AISC Connection Prequalification Review Panel in accordance with Chapter K of the Seismic Provisions for Structural Steel Buildings. The connections have been prequalified for use in special and intermediate steel moment frames without the need for additional testing.

Supplement No. 1, ANSI/AISC 358s1-18 adds slotted web moment connections to the standard. In addition, the supplement includes a field bolted option for the popular SidePlate moment connection. The supplement has been fully integrated into the standard.

Supplement No. 2, ANSI/AISC 358s2-20 expands the scope of prequalification for the Chapter 11 SidePlate moment connection and the Chapter 12 Simpson Strong-Tie Strong Frame moment connection.
