The American Institute of Steel Con

The American Institute of Steel Construction (AISC) maintains a Connection Prequalification Review Panel (CPRP) that develops an American National Standards Institute (ANSI)-approved standard, AISC-358 Prequalified Connections for Special and Intermediate Moment Resisting Frames for Seismic Applications. AISC 358 presents materials, design, detailing, fabrication and inspection requirements for a series of prequalified moment-connection details. This standard is referenced by the code, and connection prequalifications contained in the standard are acceptable to most building officials. AISC updates and reissues this standard from time to time, as additional research becomes available. The connections in AISC 358 are not interchangeable; there are limits of applicability for each. Figure 2 through Figure 6 show the configuration of connection technologies currently included in AISC 358.
