Abstract : The design of shock isolation systems for equipment and personnel platforms within aboveground and underground hardened structures is explained by the use of both the shock spectra and the velocity pulse techniques. Ground motions are explained and their pertinent quantities are defined; the effect of the structure supporting the shock isolation system is considered; and methods are presented to obtain the response of practical isolation systems. Design procedures are outlined with frequent use of numerical examples; and tolerance levels are summarized, so that the calculated responses of designed systems may remain within acceptable limits. The report also gives a descriptive account of almost all the major shock isolation systems that have been installed at various military facilities. (Author)
