Combined Effects of Nuclear Weapons on Nfss Type Structures
The primary objective of this program was to examine and evaluate the protection afforded by the types of structures found in the National Fallout Shelter Survey (NFSS) against the combined effects of nuclear weapons. Since a major criterion for the designation of the NFSS structures was the radiation protection factor (PF) of the structure, the approach adopted in this investigation was to examine the sensitivity of the PF for idealized building situations to alteration by air blast and fire damage. To accomplish this, interim techniques were developed for estimation of the air blast loading and damage to selected types of structures. These techniques were developed by utilizing available experimental data together with engineering judgment to modify current generalized blast loading schemes. The procedure adopted to predict damage was to determine the blast loading on each building component and then to compare this loading with the failure loading for the component. Similarly, by utilizing fire prediction information, a method was developed for determining the fire damage within the building. To predict damage to the various building elements by this procedure, the duration of the peak fire was calculated and then compared with the rated resistance of the components. (Author)
