AISC 358 Connection Types and Limits
Connection design can get complicated when a building is located in a high seismic region. These connections require a significant amount of inelastic deformation in order to safely resist strong seismic activity. After the Northridge earthquake in 1994, many connection failures found in the aftermath allowed code officials to investigate and make changes to prevent these types of failures from recurring. One of the many results from this incident was the eventual development of the prequalified moment connections contained in AISC 358.
In June 2017, Matt Mester, PE, SE from SidePlate Systems, Inc. presented Moment Frames: Design and Detailing per AISC 341 and 358 for SE University. Matt reviewed all of the prequalified moment connections contained in AISC 358 and discussed the restrictions and limitations for when these connections can be used. He presented several useful charts which show each connection type included in AISC 358.
