Verification of steel constitutive models in Japanese and European fire-resistant design codes
Takeshi Okabe

Simulations are conducted using constitutive models of structural steel at elevated temperatures described in Eurocode 3 and the AIJ Recommendation, and the analytical results are compared with existing column test data. Based on the calculated results using s-e curves in the AIJ Recommendation, we obtained somewhat conservative failure times, which are, thus, on the safe side. In addition, the calculated behavior with the s-e curves in Eurocode 3 seemed to reproduce the experimental values accurately except that the calculated displacement was slightly larger than the experimental displacement.

Key words: High temperature, ? curve, Eurocode 3, AIJ Recommendation , Steel column, Fire-resistant design
