Publicada By Víctor Yepes Piqueras - algoritmo, energía, estructuras, investigación, Puentes An automated procedure for optimizing the design of structures is presented. There is a parabolic relation between the span length and the minimum energy. The energy reduction has an average cost impact of 3.23€ per square meter of deck.
