This report documents the stress-strain behavior of a collection of structural steels recovered from the collapse of the World Trade Center. These steels, combined with literature data form the basis of a model for the stress-strain behavior of structural steels in general. The model accounts for the lost of strength, the decrease in work hardening and the increase in the strain-rate sensitivity with increasing temperature. For general structural steels, it takes the measured yield strength as its only input parameter. The new model predicts the stress-strain behavior of the steels slightly better than the existing Eurocode~3 stress-strain model.
