Through examples spanning three continents, Moore unites old standbys with unexpected wonders, all of which show the varied possibilities inherent in mixing water, aggregate, and cement. “Concrete has the ability to be primitive and technological, massive and levitating, to combine the properties of steel with those of mud,” says Rowan Moore in his list of The 10 best concrete buildings created for The Guardian. In structural terms, they are efficient because they resist compression efforts and absorb at specific points on their surface, especially near the supports - small moments of flexion.
The shells arise from the association between concrete and steel and are structures whose continuous curved surfaces have a minimal thickness thus they are widely used in roofs of large spans without intermediate supports. The importance of the structural thought that culminates in the constructed object is then, taken by the relationship between form and structure. Thus, you can't conceive a form without automatically conceiving a structure and vice versa".
Every form has a structure, and every structure has a form. "You can't imagine a form that doesn't need a structure or a structure that doesn't have a form. However, if we bend it, the sheet achieves a new structural quality. If we tried to stiffen it from its primary state, it couldn't support its own weight. En esa época ya todo lo firmaba Ramírez Vázquez, pero luego de la Bolsa de Valores, como proceso de desarrollo de las ideas vino El Altillo con bordes libres, pero con una bóveda por aristas.”Įxtract of the interview to Fernando López Carmona by Lucia de la Mora y Enrique de la Mora Askinasy. Posteriormente hubo muchas intrigas, incluso se decía que nosotros habíamos construido la bóveda del Centro Asturiano (de Álvarez Ordóñez y Heberto Castillo) que se cayó. Tuvimos que adelgazar el manto y tronó al momento del descimbrado, pero después las reemplazamos antes de quitarlas por completo. En el proceso de la obra se rompieron las patas de la cimbra, pues estábamos obsesionados con la estructura ojival y las curvas nítidas de la bóveda, porque éstas deberían juntarse en el piso. El proyecto de la Bolsa ya estaba terminado, Candela entendió muy bien la lógica de la bóveda por arista con dos paraboloides hiperbólicos y así que se trabajó la idea con su cálculo, pues había mejorado el presupuesto del proyecto de González Flores que quería hacer una maqueta en madera muy costosa. Y al día siguiente estaba Félix Candela con nosotros. Pero en ese entonces, un dibujante del despacho se me acercó y me dijo: “Hay un guachupín que hace esas cosas”. Leonardo Zeevaert, quien era el Papa de las estructuras, en el sentido litúrgico, nos dijo que no funcionaría, así que fuimos con Manuel González Flores, quien también tenía muchos pantalones y era muy astuto. Él quería hacer la bóveda con una gran constructora, pero luego de que es entregamos los planos regresaron diciendo que sin duda el proyecto pasaría a la inmortalidad, pero que para realizarlo nosotros debíamos calcularlo. “Ya sé como vamos a hacer la Bolsa de Valores, vamos a hacer el crucero de La Purísima” llegó a decirme un día el arquitecto.
#FELIX CANDELA ARQUITECTO FREE#
At that time, Ramírez Vázquez signed everything, but after the Stock Exchange Building El Altillo came with the development of the ideas of free edges domes.” People even said that we had built the dome of the Centro Asturiano (from Alvarez Ordoñez and Heberto Castillo) that fell down. However, we could replace them before removing it completely. We had to thin the section and it broke when we removed the de formwork. During the construction process the legs of the formwork were broken because we were obsessed with the ogival structure and the sharp curves of the dome. Candela understood very well the logic of the dome with two hyberpolic paraboloids and we worked with that idea using his calculations that improved the budget of the Gonzalez Flores that wanted to do a very expensive wood model. The project of the Mexican Stock Exchange was finished.
At the same time Felix Candela was with us. However, at that time a drafter in the office came to me and told me “There is a guy that makes these stuff”. Therefore we contacted to Manuel González Flores who was also very good and astute in the field.
Leonard Zeevaert, the pope of structure at that time, told us that it would not work. He wanted to build the dome with a large contractor, but after sending the drawings, they came back to us saying that, of course, the project would be unforgettable, but we had to calculate it. “I know how we are doing the Bolsa de Valores, we are doing the transept of La Purísima ” the architect told me one day.
