Critical Loads for Reinforced Concrete Bunkers.
Abstract
Among the targets of interest for nuclear weapons are underground bunkers of reinforced concrete construction. The Defense Nuclear Agency is conducting a program to obtain the failure loads of shallow-buried bunkers subjected to air blast waves acting on the ground surface. The blast waves of interest are those from a nearby nuclear weapon of 1-kton yield detonated on or above the ground surface. This report describes a simple conceptual framework for interpreting experimental and theoretical load-damage results. This framework consists of a Pressure-Impulse characterization of critical loads for the bunkers. The procedure for obtaining the characterization simplifies the prediction of damage to box bunkers caused by ground surface loading. It requires further development for improvement of the simplifying assumptions and comparisons of damage predictions with experimental results. (Author)
