Abstract : The results are presented of a study devoted to the establishment of basic criteria and shock isolation techniques applicable to hardened civil defense shelters for protection of personnel and equipment against ground shock effects from nuclear weapons. The report includes a comprehensive review of the state of the art covering background information from which are established ground-shock input data and shock spectra, personnel and equipment shock tolerance criteria, and appropriate shock-isolation methods. General shock isolation schemes, including spring systems and cushioning materials, are evaluated. Design examples and cost estimates of specific shock isolation systems are presented and discussed for shallow-buried structures with populations of 10, 100 and 250 persons at the 25-, 100-, and 300p.s.i. blast overpressure levels for a 20-MT surface burst. Recommendations for further study are given.
