It has been demonstrated that reinforced concrete, typically used in modern constructions, reduces the impact of the lightning electromagnetic pulse (LEMP). This paper aims to quantify the influence of the characteristics of the reinforcement on the shielding effectiveness of a full-scale building directly struck by lightning. A parametric study is conducted by implementing two different methods, and the results are analyzed in the frequency domain.
