The pylon is much heavier than the deck, and thus gives us the impression bridgf it alamiplo the principal member in the load system, but still has many design subtleties to reduce alsmillo impact.

The diversion of the river resulted in the creation of Cartuja Island, an artificial island named after the Cartuja Monastery that is located there. Erection of the steel segment of the pylon and welding to the previous segment Placement and tensioning of a couple of cables Placement of reinforcing steel and concrete filling of segment The design and construction of the Alamillo Bridge provides an insight into one the best Architectural and Engineering minds of our time.

The elegant design of the Alamillo bridge has been copied numerous times by other architects and many bridges around the world now feature a similar design. Each of its two 10 meters 33 feet carriageways cantilevers five meters In the event, for both economic and political reasons, only one was built, and has remained an icon of bridge design and engineering ever since.

Construction of the bridge began in and brideg completed in from a design by Santiago Calatrava.

Seville Andalusia — Spain. They realised that small variations in the weight of the tower almaillo the forces in the cable stays could affect the safety of the bridge Consequently adopted a sophisticated quality control system to check the weights as built and to measure the forces in the cables.

The construction designers and advisors showed that this was too risky – proper safety levels could not be reached. The Alamillo bridge, meter feet long with a maximum span of meters feetis characterized toward La Cartuja island by a pylon, meter feet high and inclined 58 degrees on the horizontal.

See slideshow pictures 26,29 Cables: Santiago Calatrava Valls, a Spanish neofuturistic architect, structural engineer, sculptor and painter designed Alamillo Bridge. Unfortunately in escalating cost estimates led to the decision to scrap the design for a second bridge across the Guadalquivir. In practice this is impossible.

They realised it was possible to backfill part of the river underneath the bridge and erect temporary supports. The inclined pylon also emphasises the male form, while Btidge himself cites a flying bird as his main inspiration. Between the mast and the deck is a balance of forces, which are transmitted by the rbidge pairs of suspender cables. Of all the new bridges that were planned for Expo ’92, the design for the new Alamillo Bridge, planned just north bidge the expo site, was the most eye-catching.

Alammillo box girder comprises welded steel plates with Bridge Deck: So imagine the flow of those forces through the structure.

Retrieved from ” https: Pairs of cables are taken down from the pylon in a harp arrangement, meeting the deck either side brisge the pedestrian walkway. The bridge is especially beautiful at night, when it is illuminated. Cables The cables are made up of 60 cords of 6 inches in diameter each, except rbidge last couple brkdge m in length, consisting of only 45 cords. See slideshow pictures and The bearings sit on the foundations.


Iron, carbon with other additives such as chromium etc Concrete: The beam works by bending but can only do that if it is supported – by bearings at the far end from the tower, by cables at intervals along its length and by the foundations under the tower that clamp the deck, tower and foundations together.

Alamillo Bridge, Seville

In this initial project, only one was erected, because the budget was not sufficient to cover the pair. Cookies We are using cookies to provide statistics that help us give you the best experience of our site.

The pylon supports the bridgeway with thirteen pairs of cables. After the Guadalquivir, the main river flowing through Seville, had caused several major floods, government decided to reroute the river to the west. The most distinguishing aspect of the design is the meter ft tall pylon, which is gracefully slanted at an angle of 68 degrees. From the counterbalancing pylon, pairs of cables support a central spine beam of prefabricated hexagonal shaped steel box sections running the full length of the bridge, from which the road deck itself cantilevers transversely.

Calatrava provided a fresh take on the idea with the Puente de la Mujer in Buenos Aires, a bridge that opens to river traffic. The bridge deck consists of an hexagonal, steel box beam spine to which the stay cables are attached.

Transmit tension and consist of 60 steel strands mostly – the longest stays have 45 each 15 mm.
