Finite element modelling of thermo-elastoplastic behaviour of hot-rolled steel profiles submitted to fire
Orientador(es)
Resumo(s)
This paper presents finite element algorithms developed to simulate the thermoelastoplastic
behaviour of steel profiles under high temperatures, in particular those arising
from fire conditions. Transient analyses of the temperature field and the mechanical response
at each instant have been done. The thermal response obtained with the finite element
formulation and the results obtained using the simplified heat conduction equation according
to the Eurocode 3 have been compared for several series of hot-rolled steel profiles. The nonlinearity
of the problem due to the thermal dependence of the material properties has been
taken into account and an elastoplastic model has been used.
