Steel Shots: Twisted Beams
Posted by Tom Klemens on May 12, 2011 at 11:02 PM.



A full-size test specimen of ConXtech’s ConXL special moment frame (SMF) connection - after being tested - is one of the interesting things to see in the Exhibit Hall this year at NASCC: The Steel Conference.


Full-scale testing of large structural steel connections produces some pretty convincing results. This 6-ft section of a test specimen on display in the ConXtech booth (#1229) at NASCC shows convincing proof that the 30-in wide-flange beams failed before the company’s ConXL connection. Put another way, this proprietary, rapidly connected “lower and lock” connection system develops the full plastic moment of the beam. The connection has been prequalified by the AISC 358 Connection Prequalification Review Panel and will be included in the 2010 Seismic Conditions.
