Effects of Fire on Structural Debris Produced by Nuclear Blast

摘要

The chief objective of this phase of the program is to evaluate fire effects on debris produced by nuclear weapons. The magnitude of fire from nuclear weapons as a major agent of destruction is discussed. The aftermath of blast and fire is then evaluated in terms of debris. Fire effects on specific types of structures, are discussed with respect to determination of resulting changes in debris quantities. Data from major fires are used to augment this portion of the study. The percent of debris vs overpressure curves (developed in the first phase of the program to predict the amount of debris formed by air blast) are altered to reflect the coupled effects of blast and fire. An example employing data, techniques, and knowledge developed in the program is presented. This takes the form of determination of debris depths along a route through a stricken city. (Author)
