In this study the design sensitivity of blast-resistant door composed with steel plate and inner RC core was analyzed according to increased steel ratio of plate and rebar. The results showed that compressive failure of inner concrete decreased rapidly in the case of specific steel ratio, and that the overall structural performance such as deflection did not changed substantially.
