This paper investigated impact resistance capacity and failure mode of strengthened column with PROTECT (Poly-Resilience-Oriented hybrid TEChnology plaTe) panel by analytical study. PROTECT panel is the composite panel with two steel plates and nano-composite. In order to perform impact analysis, dynamic properties of concrete, steels and nano-composite were determined. Finite element analysis was performed with these properties under the drop-weight impact. From the FEA, different failure modes corresponding to different columns were derived.
