ANSI/AISC 358 Prequalifies SidePlate Connections for Seismic Applications

Seismic Industry’s Latest Standard Includes Chapter on the Qualifications of SidePlate Connections, Making it Even Easier to Work With the Industry’s Leader in Structural Design Optimization

Business Wire


SidePlate®, a Berkshire Hathaway company (NYSE: BRK-A, NYSE: BRK-B) that designs innovative steel lateral frames, today announced that their connections have been included in Supplement No. 2 of the national standard ANSI/AISC 358-10, “Prequalified Moment Connections for Special and Intermediate Steel Moment Frames for Seismic Applications.” This prequalification, which resulted from a thorough examination by AISC’s Connection Prequalification Review Panel (CPRP), makes great strides in assuring seismic engineers, designers, fabricators, and specifiers that SidePlate’s connections are a safe and code-approved choice.

The recent ANSI/AISC prequalification of SidePlate connections is just the latest in a string of similar prequalifications for SidePlate solutions that reach back two decades. SidePlate connections have been prequalified by numerous other local, state, and federal agencies, including ICC-ES, DOD, OSHPD, and DSA. Moreover, the ANSI/AISC prequalifications in Supplement No. 2 go well beyond those of other moment connections listed in the ANSI/AISC 358-10 standard, including biaxial connections, HSS beams, and the deepest allowable beams (W40).

All of SidePlate’s innovative design options are implemented with the help of responsive, attentive structural engineers who provide assistance and customer service at no charge to the design team, as well as construction phase services to fabricators and erectors.

“The ANSI/AISC prequalification is the ‘gold standard’ for assuring seismic engineers and fabricators that they can implement SidePlate connections with confidence and without concern for additional review and approvals,” said Henry Gallart, SidePlate’s president. “The fact that SidePlate holds many such prequalifications only underscores the fact that our connections are so widely recognized. Indeed, they are on the way to becoming industry standards.”
