Félix Candela, the great Mexican-Spanish architect, was taking part in the design of a roof for the restaurant of the new Aquarium that was being designed in Valencia (Spain) in the late 1990s. Unfortunately, he passed away in 1997, leaving just the basic geometry of the shell, which should be a re-creation of the renowned "Los Manantiales" roof in Mexico City. This lecture presents the challenges faced and the solutions we found to design and build the shell roof according to Candela's philosophy in a context where the knowledge of designing and building thin concrete shells was practically lost. It also highlights the importance of understanding and learning from the works of our master predecessors.
Prof. Lázaro is a Civil Engineer and a Doctor in Structural Engineering. Currently he is Associate Professor at the Department of Structural Mechanics of the Universidad Politécnica de Valencia and visiting Professor at the Techincal University Munich. He is President of the International Association for Shell and Spatial Structures (IASS).
His research interests cover computational solid mechanics with emphasis on models for slender rods, the design of movable structures and active bending structures, and the application of fibre reinforced and recycled concrete to structural design.
Prof. Lázaro was founding partner of the design, engineering and architectural firm CMD Ingenieros. Within this environment, he has designed and assisted the construction of thin shell structures (such as the hypar roof in L’Oceanografic in Valencia) using fiber reinforced concrete, urban bridges (Jucar Bridge in Cullera, and Turia Bridge in Manises), and spatial structures and buildings as the roof of Xativa's arena, the 130 m tall Alphabetic Tower in Batumi (Georgia), or the New Parliament building in Kutaisi (Georgia).
