Vital structures such as nuclear plants, power plants, military structures, weapon industries, weapons storage places, bunkers, water retaining structures (dams, barrages, etc.), chemical and local industries, highway and railway bridges, tunnels, flyways, barriers etc have to be designed as self-protective structures against impact loading generated by natural disaster (tsunami, hurricane, tornado, wind storm, sand storm and earthquakes etc),...
