| Sumario: | [EN] Reinforced concrete precast hinged frames are commonly used in transportation infrastructure. Advances in optimization techniques lead to improvements in the traditional structural design process. These allow for minimizing factors such as the final cost of the structure. The present study developed the economic optimization of a reinforced concrete precast hinged frame. In order to do so, the hybrid metaheuristic technique of simulated annealing with a mutation operator was applied. The algorithm parameters were tuned by means of a factorial Design of Experiments. This allowed the algorithm to show excellent performance. Once tuned, the hybrid metaheuristic was applied, achieving designs with reduced final costs. Finally, a series of main characteristics are mentioned. The designs present reduced depths and considerably dense passive reinforcement designs. The results obtained position the precast structure as a particularly interesting alternative to similar cast in place structures |
