A survey was conducted of available dynamic test data and current in-structure shock analysis techniques. Simplified semiempirical, single-degree-of-freedom, and two-dimensional 2-D finite-element, in-structure shock analyses of buried reinforced concrete structures were conducted. Analysis results were compared to test data. An evaluation of the analysis techniques was completed, and a technique was selected for further development as an in-structure shock analysis tool. The technique selected for further development, based on this evaluation, is the explicit 2-D finite-element program ISSV3. Extensive comparisons of the results of the in-structure shock analysis of the test configurations, using the available methods, show ISSV3 to be fast, accurate, and easy to use.
