The present study deals with optimal design of arrays of protective structures. The structures, intended for storage of explosive materials, consist of rectangular reinforced concrete RC plates, beams, and doors. The design variables include a The elements cross sectional dimensions b The structural configurations c The glometric location of the structure. The constrains are related to safety distances, functional requirements, and structural behavior. The objective function represents the cost, including cost f materials, real estate, subgrade, maintenance, etc. Approximate behavior models are employed in order to simplify the analysis. Since it is not practical to optimize all the design variables simultaneously, it is proposed to use a multilevel optimization procedure. The variables are optimized in different levels, according to their type and nature. Considerations for choosing the levels are discussed and numerical examples illustrate the approach and its practicality.
