NIST-ATC Blind Prediction Contest – Deep, wide-flange structural steel beam-columns

OPEN NOW!
The purpose of this contest is to assess the uncertainty in the predicted response of steel beam-columns by predicting the response of three beam-column test specimens. Submittals are due December 22nd and the category winners will be awarded at the AISC Steel Conference (NASCC) in Baltimore, Maryland on April 10-13, 2018.
