Abstract : The report presents the results of a project to test and evaluate four computer programs developed by the Office of Civil Defense, in order to determine their usefulness in engineering analysis or review of protective structures for civil-defense purposes. The programs are (1) Dynamic Response of High-Rise Buildings to Nuclear Blast Loading-Linear Dynamic Analysis, (2) Dynamic Response of High-Rise Buildings to Nuclear Blast Loadings-Nonlinear Dynamic Analysis, (3) Analysis of Structures for Fallout Gamma Radiation Shielding, and (4) Reusability of Buildings after a Warfire. Two actual high-rise building designs, a reinforced-concrete frame structure and a structural-steel frame structure, were used as prototypes for the evaluation. The programs were used to perform analyses to determine necessary structural modifications to incorporate blast and fallout protective design features in the original design of each building for the 2,5 and 10 psi overpressure ranges for a 10-MT nuclear weapon. The fire protective capability of the buildings for each protective design was also evaluated. Structural modifications and incremental cost are presented in the form of engineering case studies. A comparison of computational costs for the test buildings by the computer method used, with costs estimated assuming the analyses were performed by manual methods is presented. Other evaluations were made pertaining to (1) input forms and computer operation, (2) economies of design, (3) completeness of programs, (4) flexibility of programs, (5) use of the programs separately or together.
