Can a metallic sheeting replace the bracings to resist the lateral forces - seismic forces and wind forces, to add stability of the structure?

I have a slender structure, 5 m x 2.4 m of height 18 m. I wanted to replace the lateral bracings from level 6 m and above with the metallic sheeting, 6mm or more. I have added the plates of thickness 6mm to simulate the sheeting and by adding intermediate members to limit the supported area of sheeting by 1.1 m x 2m. How can I verify if this design is safe according to Eurocode?
