Abstract


The paper presents this technology, that responds to the author’s initial idea of using tension advantages in footbridges. It begins with a brief analysis of the membrane structures and the challenges associated to this new application.
Emphasis is made on a research project associated to the design, construction and testing of a membrane footbridge in Callús (Barcelona). Its global objective was making real the idea, materialising such a footbridge on the ground and thus verifying its functional, structural and constructive aptitude. There were also partial objectives linked to structural analysis (suitable formfi nding method for membrane and edge cables), design, construction process, environmental impact and serviceability behaviour, so leaving to specifi c conclusions.
Of course, such research (due to an agreement between CSIC, FECYT and the Council of Callús) is described with some detail in all its stages:
1, Footbridge design (mainly, the structural membrane).
2, Footbridge construction at Callús.
3. Footbridge testing.
The results were positive and the prototype fulfi lled its mission of making real an idea. Starting from it, the main conclusion was to continue the study of this membrane technology (something not at all obvious before the Callús project).
Finally, after an evaluation of the technology, a brief discussion about continuity and prospective of such a work line is presented. In this way, the perspective of reaching long spans by using this technology (much improved) is pointed out.
