Abstract
The “Modern Architecture´s Thin Shells Adventure” started in the twenties, when the reinforced concrete was still developing and a new “air” – Modernity – was born. At that time, and during the following decades, it was very difficult to design thin shells because computers, as we know nowadays, did not exist and the existing tools to calculate such shells were very complicated. Also it was difficult to guarantee the right structural behaviour of this new structural form, being slender, light and big in size. This was the reason why in the 1930´s Eduardo Torroja developed the reduced model test to check the structural behaviour of this new structural form. In 1941 the Spanish engineer Ildefonso Sánchez del Río presented, at the Eduardo Torroja Institute, his own and innovative system design for shell structures. During three decades he built a lot of thin shells using his system design, like the Oviedo Sport Palace (100m span) and the Pola de Siero Market, which were published in the covers of the IASS bulletin.
