Fire or earthquake pose a significant threat to the human life, and can cause an enormous damage to the structures, moreover the dual effect of a Post-Earthquake Fire (PEF) is a major hassle to designers and rescuers alike. The experiments carried out by Petrina (2016) [1]; show that post-earthquake fire produces serious damage to the structural elements after their load resistance has been altered by a seismic action. Extensive research to study the behaviour of unprotected and protected steel structures [2-3] has been done, and yet there is still a great need for the understanding of the behaviour of structures damaged by earthquakes and exposed to fire.
Fire or earthquake pose a significant threat to the human life, and cause an enormous damage to the structures, moreover the dual effect of a Post-Earthquake Fire (PEF) is a major hassle to designers and rescuers alike. Designers, when considering Algerian seismic rule (RPA99v2003) [1], ignore the possibility of a post-earthquake fire, whose effect can lead to the dramatic collapse of the structures.
