摘要：The study of the influence for design solution detailing on the cost of reinforced concrete structures during their optimization is carried out. A hypothesis is formulated on the final improvement of the target criterion with an increase in the number of variable parameters. Depending on this number, the concepts of three levels of detail are introduced, at which optimization can be carried out, and the degree of risk of failure of the structure is indicated for them. Using the example of finding a constructive solution for a reinforced concrete beam by the cost minimization criterion, the relationship of the cost change is shown when the number of independently variable parameters changes. The normal operation of the beam and the emergency action effects in the form of local damage to a single corner connection are taken into account. Genetic algorithms are used for the optimization.
