Through the use of equivalent variable analogies, the authors demonstrate how an electrical subsystem can be modeled by an equivalent structural subsystem. This allows the electrical subsystem to be probabilistically analyzed using available structural reliability computer codes, such as NESSUS. With the ability to analyze the electrical subsystem probabilistically, the reliability of systems that include both structural and electrical subsystems can be evaluated. Common examples of these type of systems include a structural subsystem integrated with a health monitoring subsystem and smart structures. These systems involve electrical subsystems that have a direct effect on the operation of the overall system. Probabilistic analysis of these systems will lead to improved reliability and reduced cost. The direct effect the electrical subsystem will have on the structural subsystem is of secondary order and is not considered in the scope of this work.
