Eduardo Torroja Miret

To understand the work of Eduardo Torroja Miret, considered in his time as a creator and innovator within the field of structures, it is necessary to reread the prologue of his book “Razón y Ser de los Tipos Estructurales” ("Reason and Being of Structural Types"), in which the author himself tells us:

Each material has a different specific personality, and each form imposes a different tensional phenomenon.
The natural solution of a problem – art without artifice -, optimal in front of the set of previous taxes that originated it, impresses with its message, satisfying, at the same time, the demands of the technician and the artist.
The birth of a structural whole, the result of a creative process, a fusion of technique with art, of ingenuity with study, of imagination with sensitivity, escapes from the pure domain of logic to enter the secret frontiers of inspiration.
Before and above all calculation there is the idea, moulding the material into a resistant form, to fulfil its mission.
This book is dedicated to that idea.

Calculus Decreasing for Eduardo Torroja

Since the mid-sixties, to the not unique but predominant influence of the Portuguese poet Joao Cabral de Melo, was joined in Gabino-Alejandro Carriedo, by hobby and professional dedication, the interest in the work of architects, sculptors and painters Spanish and universal contemporary, resulting in the book libro Los lados del cubo (The sides of the cube), published in 1973. It included the elegiac poem Calculus Decreasing for Eduardo Torroja, which paid tribute to the famous civil engineer, designer, scientist, manager and teacher; born almost with the century and died prematurely in 1961.

1. Entre el puente de hormigón
(construido aguas arriba
de su corazón valiente)
y la cubierta circular,
expiró el ingeniero.

2. Ni la luz de aquel vano
alzado en vigas longitudinales
prefabricado por dovelas
salvarlo pudo
de las sombras.

3. Ni los cordones de los cables
de redondo
calculados para tan fiel tensión
evitaron su rotura.

4. Su vida matemática

5. Cosido transversal,
definitivo anclaje.

6. In situ.
