“…Over the last two decades, studies on the design optimization of granular-solid prismatic beams have received considerable attention. Prakash et al (1988); Ezeldin (1991); Quiroga and Arroyo (1991); Erbatur et al (1992); Al-Gahtani et al (1995); ; Lepš and Šejnoha (2003); Barakat et al (2003); Govindaraj and Ramasamy (2005) and Kwak and Noh (2006) attempted to seek optimal shape of beam cross-sections. They highlighted the potential savings in material, either directly or indirectly through various optimization techniques analogous to shape and sizing methods.…”

“…• En 1992 Erbatur et al [56], emplean el método simplex para la optimización de peso y coste de vigas de hormigón pretensado biapoyadas, aplicable a cuatro posibles secciones, sometidas a limitaciones de flexión (ELU y ELS), limitaciones de flechas en tres momentos de la vida de la viga, e incluso una comprobación de pandeo, que se justifica por la importante esbeltez de las soluciones óptimas. Las variables de decisión se reducen al ancho de la sección y la fuerza de pretensado.…”
