Structural behavior of blast-resistant door composed with steel plate and inner con’c core was analyzed according to composite and non-composite condition. The results showed that maximum and permanent deflection decrease in the case of composite condition. And as the impact on blast-resistant door increases and radical deformation occurs, there is not much difference in the deflection of the door.
