Earthquakes and explosions are the most destructive dynamic loads that can cause
severe damages to the structures.Due to the difference in the nature of blast and earthquake loads, there
has been very little research in this area, which doubles the importance of the issue. In this research, a two-dimensional three-spanned RC frame with three floors was modeled and analyzed using ABAQUS/Explicit finite element software. Twelve different scenarios of concurrent earthquake and explosion
loads are considered and the most critical simultaneous state is identified here.
The most important findings show that in all three modes of explosion location
including in front of the frame, lateral explosion and internal explosion, in the case
where the seismic load and the explosion are orthogonal to each other, more
damage is observed in the structure in compare to the case of aligned loading.
Damage caused by explosion in frontal explosion mainly affects the columns and
foundation of the column. Damage caused by lateral explosion mostly affect the
beams. And finally, damage caused by internal explosion, affect the beams and
columns of the span where the explosive is located. Among the scenarios in which
the explosion occurs during earthquake's strong movements are more critical than
the scenarios in which the explosion occurs before the earthquake
