Abstract

The present study is focused on optimal design of bending reinforced concrete elements and structures working in aggressive environments. A peculiarity of this research is checking the possibility of direct application of Dolinsky's corrosion model to the reinforcement which is considered as a round section rod loaded by axial tensile force. The model considers the influence of the stress state in the rod on the corrosion kinetics. The objective function is the initial cost of a unit length of a reinforced concrete element, consisting of the reinforcement and concrete costs. The initial dimensions of the reinforced concrete element rectangular section, as well as the number of reinforcement bars, are optimized. Taking into account corrosion, using the Dolinsky model, applied directly to reinforcement, allows assessing the dynamics in the corrosion process during a given period of the structure operation, as well as predicting an increase in its initial cost.
