Idelfonso Sánchez del Río is a less known pioneer of reinforced concrete shells in Spain who through his career designed and patented ribbed construction systems for large spanning slabs and vaults and in particular shell enclosures using a hybrid system of concrete and masonry infills. The module called “dovela-onda” or wave-voussoir was made of large ceramic blocks forming a short barrel with flanges at the edges. This paper aims to discuss the technical innovations of this system and assess its structural efficiency. The design and construction process will be studied through literature published by Sánchez del Rio and surveys of two case studies in Oviedo (Spain), the Sports Hall (1977) and a warehouse in Granda. In order to assess their structural efficiency, his own calculation process will be verified by thrust line analysis and Finite Element spatial elastic modelling. The FE model allows the failure mode and the distribution of the loads to be assessed, and gives further insight to the behaviour of the scheme and the design and construction process.
