The development of Structural Fire Engineering over the past 25 years and issues for the future

This talk presents a series of thoughts of the author from his observation of the evolution of structural fire engineering since the beginning of his career
Experimental research works are discussed, either on the behavior of materials or on the behavior of structures. The rest of the presentation is dedicated to calculation methods: tabulated data, simple calculation models and general calculation models. For numerical calculation models, the presentation contains a brief history of appearance of different software, of their objectives, of their capabilities… Some examples are presented of structures recently modelled in real applications. Possible abusive utilizations of numerical modelling are also shown.
The presentation ends with a presentation of some challenges that the discipline is facing for the future.
