Abstract:

Protective structures designed to withstand the effects of conventional nonnuclear munitions are built primarily according to deterministic design procedures. Real world variabilities in site characteristics, structural attributes like strength and stiffness, and weapon delivery characteristics are generally not accounted for in current design schemes. This report shows the feasibility of developing a balanced design tool which 1 takes into account the natural random variability of quantitative design parameters 2 provides a framework for assessing the uncertainty in nonrandom issues such as modeling and boundary conditions assumptions and 3 accommodates flexibility in modeling various structural response physics caused by evolutions in weapons environment. This report presents results illustrating the advantages of considering variability in the design process. A proposed integrated design system appears feasible which would explicitly show how information form design handbooks, research findings, and expert knowledge, and stochastic method can be collected together in one place. Design tools, which are capable of considering the influence of natural variability in materials and loads on cost and survivability, will have tremendous value to the Air Force in its planning cycles for new hardened facilities and for necessary field modifications to existing structures.
