Phase 2 of NIST-ATC Blind Prediction Contest: Deep, wide-flange structural steel beam-columns

Now Open!

In Phase 2 of the blind prediction contest, the participants are asked to predict the response parameters for Columns B and C by having access to the experimental results for Column A. The objective of Phase 2 is to assess the change in the uncertainty of predicted response of wide-flange structural steel beam-columns if, in addition to all of the data made available during Phase 1, the overall lateral load-lateral response of Column A is also made available.
