ABSTRACT
One of Heinz Hossdorf’s most prominent contributions was the creation of his so-called “mixed rims” in reinforced concrete thin shells. This system consisted in connecting a steel truss to the rim of a concrete shell so that the two would contribute jointly to the structural performance of the whole. He used this new system in the Gossau Industrial Bay in 1954. Félix Candela later drew from this bold structural resource, using other steel elements and geometries, in some of his thin shells, such as in San Antonio de Huertas Church (1956).
