Structural design in the work of Gaudí

Abstract

The work of Gaudí embraces all the facets of architectural design. The present paper studies the analysis and design of masonry arches, vaults and buildings. It is well known that Gaudí used hanging models and graphical methods as design tools. These methods can be traced back to the end of the 17th Century. Also, it was not original the use of equilibrated, catenarian, forms. What was completely original was the idea of basing all the structural design in considerations of equilibrium. Gaudí, also, employed unusual geometrical forms for some of his vaults, ruled surfaces, showing a deep structural insight. Finally, he designed tree-forms of equilibrium for the supports of the vaults in the Sagrada Familia. In the present paper Gaudí’s equilibrium methods are studied with some detail, stressing their validity within the frame of Limit Analysis
