What is it about?
An expeditious method to compute the collapse temperature of restrained steel columns in fire is developed. It is based on a rigid-plastic model that considers the thermal elongation and the degradation of the mechanical properties with heating. It respects the Drucker normality rule for perfect palstic behaviour and accounts for the degradation of the steel's mechanical properties with heating.

Why is it important?
The collapse temperature defines the column's resistance in fire. Therefore, an expeditious method that dispenses the Finite Element modelling is wellcome at the engineering office.
Perspectives
This methodology may be applied on a daily basis at the engineering office, because it saves a lot of time when compared to sophisticated FEM modellings
