The report considers the economic feasibility of using metallic interior shear wall elements in place of conventional reinforced concrete shear wall elements in hardened facilities. A simplified, aboveground two story building is designed using both conventional concrete and metallic shear wall elements. Five combinations of weapon yield and overpressure are used to size the building elements. Three wall configurations are considered reinforced concrete, low yield strength steel A-36, and high yield strength steel A-514. Total facility and shear wall costs are compared. Based upon a somewhat limited use of metallic materials, it is nonetheless clearly indicated that the use of metallic interior shear walls can substantially reduce facility structural costs by as much as nine percent at low overpressures. Comparing the in-place wall costs, savings on the order of 50 percent are possible under some design requirements and metallic material properties. Author
