Ramón Araujo Building with steel: form and structure in continuous space In the 19th century introduction of iron in building triggered what was an unprecedented convulsion in architectural history. Accompanied by the increasing pre-eminence of glass, which began to be produced industrially, this technological event paved the way for the two greatest emblems of modern construction: the skyscraper, and structures of huge sweeping spans. The latter are the subject of this text by Ramón Araujo, a professor of Construction at Madrid’s School of Architecture. The article is a chronological account spanning from historical typologies, such as the grand station or the crystal palace, to the tectonic solutions based on space frames, metallic shells or pre-stressed systems that characterize our own century.

José Jurado Egea Sublimated iron The key to understanding the far-reaching developments in architecture that the use of steel has brought about lies in the physical properties of sublimated iron. In the following article, architect José Jurado presents the diversity of forms that this versatile industrial product can come in. He lists conditions foe assembly, types of steel, and methods of protection against corrosion and fire, finally analysing connection systems, and the promising prospects of individually designed connections as the basis for the design and assembly of contemporary metal framework.

Isabel Bravo Spanish-Portuguese Center in Zamora Manuel de las Casas On the banks of the Duero River, facing Zamora, and on the site of the old convent of San Francisco, rises the Rei Alfonso Henriques Foundation, a Spanish-Portuguese cultural institution. In a project that pays close attention to the mark of Gothic remains, Manuel de las Casas combines the consolidation and restoration of ruins with the building of new constructions to accommodate living quarters for teachers and researchers, besides the usual educational and representational spaces. The result is a functionally efficient complex that shows the city its clear-cut physiognomy through a juxtaposition of old stonework with large glazed planes and claddings of Cor-Ten steel sheets.

Javier Revillo Sport Center in Valdemoro, Madrid María Fraile & Javier Revillo Two austere volumes, containing a Swimming pool and a fieldhouse, are posed at the center of a parcel characterized by its pronounced slope. Fraile and Revillo treat this slope with great force, creating two planes at different levels articulated by the building complex. Just as forceful is the simplicity of the structure, with rolled steel trusses spanning approximately thirty meters in each space. With no ambiguities or disguises, glass concrete and steel mix together to ‘build’ a clear inner space.

Ramón Araujo Municipal Swimming Pools in Pinto, Madrid Ramón Araujo "A light, curving roof, opening up onto glazed edges and placed on a platform excavated in the ground." This project, to house municipal swimming pools in a town near Madrid, can be summarized in this way. Natural lightning and views to the exterior are the project author’s primary objectives. By placing the steel structure on the exterior of the building skin, he exhibits a special concern for the protection of the structural elements from the humidity of the interior atmosphere, defining the roof as a ‘multilayered canopy’.

Carlos Quintáns Sport Center of Gijón Salvador Pérez Arroyo Characterized by its functional versatility, the multisport center of Gijón illustrates part of the wide range of constructive possibilities that steel offers, from the thick steel plates to build-up the boxes that constitute the main columns of the grandstand to the big depth steel trusses that span nearly 60 meters, to the ribbed metal panels that are the envelope’s main element. With his customary penchant for the industrial esthetic, Pérez Arroyo conceives the building with a great measure of rationality, and takes advantage of the force of the structure so that through it, natural light can be made to reach down to the playing court.
