- Additional information
- The modelling of steel structures in fire has been done for beam structural elements where 1D constitutive laws have been used. In this work, the material constitutive model was extended for multi-axial stress analysis, including the thermo-mechanical effect due to fire. The effect of high temperatures on steel structures and the coupling with plasticity led to the development of a new multi-axial combined kinematic/isotropic hardening model so that the Bauschinger effect for steels under fire can been done in a very effective and accurate way.
