Concrete hyperbolic paraboloid umbrella shells designed and built by Félix Candela served as models for this structural optimization study. Finite element analysis and optimization of these models provide insight into how a structural artist designed his structures. Moreover, properly combined with an understanding of shell behavior, this study used modern computational tools to show how a new design could aid contemporary engineers in designing optimum types of thin shell concrete structures.
