Análisis de las deformaciones en paraboloides hiperbólicos mediante la utilización de ecuaciones de equilibrio con términos de segundo orden en desplazamientos y su resolución por diferencias finitas. Se obtienen cargas críticas de pandeo para fuerzas en cualquier dirección incluso puntuales o variable. Dentro del Departamento de...

In the summer of 1955, the Venezuelan architect Fruto Vivas met up with the engineer Eduardo Torroja in Costillares (Madrid) in order to propose collaborating on the design of a roof. The form of the shell did not come to Torroja in a complete form, but rather he had to approach it based on discussions with the author. The previous design was...

Years ago we built a large cover to demonstrate the great possibilities that the Vierendeel solution has to solve double curved roof surfaces. It was the Dos Hermanas Velodrome, a good example of this solution. Now we have planned to solve a large cantilever roof spanning 150 m and flying 34 m with a similar solution. For the Velodrome we...

Tensile fabric structures offer possibilities for the solution of urban problems which no other type of structure permits. In the Expo Zaragoza 2008 site (Saragossa, Spain) we have designed a 400 metre-long structure that has turned out to be one of leading attractions of the event. It consists of thirteen pieces of torical surface that twist...
