Structural Eurocodes are a set of 58 different parts dealing with all the aspects of the design of buildings and civil works. Among them are some parts devoted to the structural fire design. This paper gives some background information from various research projects which were carried out during the last decade to improve or fill some gaps in the knowledge to be able to understand the entire structural behaviour of a building when submitted to a real fire. Focus is made on the so called "natural fire safety concept" and on projects dealing with composite (steel + concrete) structures, as well as steel members.

Key words: Structural Eurocodes, fire design, natural fire, fire safety engineering, heat transfer, mechanical behaviour, modelling
