The analysis of buried structures designed to resist blast loading is a continuing problem in the area of engineering mechanics. The complex structural dynamic of the problem, coupled with the uncertainties of soil structure interaction, make this a difficult challenge. Even if the structure itself is designed to survive the expected dynamic loads, the shock environment inside may be severe enough to harm personnel or equipment. A thorough understanding of the expected shock environment is therefore needed to design ways to reduce this damage. The objective of this study was to conduct and evaluate in-structure shock calculations for buried reinforced concrete structures under dynamic loads from buried conventional explosives. Of primary importance was the evaluation of two dimensional explosives. Of primary importance was the evaluation of two dimensional 2-D finite-element analysis techniques applied to this complex three dimensional problem. Two personal computer based, 2-D finite-element programs, were evaluated for application to this problem.
