The occurrence of fires breaking out during a seismic event, or even delayed after an earthquake represents a common circumstance in earthquake prone Countries, which must be adequately taken into account as a possible design scenario. In fact the behaviour in fire of structures that have been damaged by earthquakes changes as respect to the undamaged ones, since the earthquake‐induced damage makes the structure more vulnerable to fire effects. In view of the current seismic design approach, where a certain extent of damage in case of severe earthquake is acceptable, the analysis of the behaviour of structures under the effect of fires in combination or following an earthquake is a significant research field, which is not yet fully explored. The robustness assessment under fire of structures already damaged to different extent by the seism, through a performance – based approach, is required. The procedure should be valuable as a design tool, as well as a vulnerability evaluation of the built heritage against FFE. In this paper the proposed general methodology is exemplified with regards to steel structures.
