| Abstract: | Steel structures are vulnerable to fire and need protection. On the other hand, in earthquake-prone areas, seismically resistant steel structures are generally designed with high ductility, which causes them to undergo significant deformations during earthquakes and, subsequently, damage to the applied fire protection coating. Considering the possibility of a fire incident after an earthquake event, understanding the fire resistance performance of seismically damaged fire protection coatings requires conducting research that is considered in this paper. In this research, a series of seismic tests (a total of seven quasi-static cyclic lateral loading tests) and a series of fire resistance tests (a total of 11 tests) have been performed on protected steel elements. The fire protection coatings considered in this research are cementitious spray-applied fire resistive materials that are widely used in the world. The parameters studied here include the type and thickness of the fire protection coating, the type of fire protection coating reinforcement system, and the intensity of the earthquake. According to the results of these tests, complete and accurate information on the fire resistance performance of spray-applied fire resistive materials against post-earthquake fire has been obtained and the effect of various parameters has been determined. In this regard, it has been found that the mechanical properties of the fire protection coating, the reinforcing system of the fire protection coating and the characteristics of the steel section are important parameters and factors.
