The cables are made up of 60 cords of 6 inches in diameter each, except the last couple of m in length, consisting of only 45 cords.

Insoon after king Juan Carlos I announced Seville would host the World Universal Exposition of to commemorate the Discovery of America, plans were drafted to improve Seville’s infrastructure. Views Read Edit View history.

Latest Issue of Built Expressions on stand. The construction designers and advisors showed that this was too risky – proper safety levels could not be reached.

Because of its boomerang shape, it only has one arm to support its entire weight. The bearings sit on the foundations. Cement, sand, aggregate and water Reinforced concrete piles: They realised that they must also allow for creep and shrinkage of the concrete in the tower.

Alamillo has a very sculptural form, and this design simplicity gives it order. The design and construction of the Alamillo Bridge provides an insight into one the best Architectural and Engineering minds of our time. Space alamilli been reserved for the machinery of a future external panoramic lift, and elevators and stairs have been constructed to connect the two. Construct temporary piers 4.

The diagram shows the nature of the internal forces – click on it to open a larger version in a new window with further explanation. The right hand diagram is a sketch showing the way the trusses are connected to the steel outer plate. The box girder and cantilevered road deck elements were initially constructed on continuous falsework, supported on the mostly dry river bed.

When all loadings and variations were considered by the construction designers and advisors and when they calculated the envelope of the possible maximum and minimum internal forces in the bridge they realised that they had to design bridge deck, the tower and the foundations to cope with very large bending moments. These forces are balanced, not by some back stays as is usual, but by the weight of the considerable backwards lean of the massive tower.


There is an excellent balance between light and dark, and the deck itself appears as a particularly slender element. The Expo ’92 World Fair provided the authorities of Seville with an opportunity to improve the infrastructure of the city and its surrounding areas in the Province of Andalusia. Mimicking the pylon, these guard rails slope backwards away from the deck, and are topped with concrete along which runs a smooth stainless steel handrail. The simplicity of the colour scheme complements the bridge design, leaving its striking form unspoilt.

The pylon was constructed by lifting segments of the steel shell into place with a large, high-capacity crane, then welding them together and filling them with reinforced concrete. The inclined pylon of Alamillo had no structural precedent.

So imagine the flow of those forces through the structure. Cables The cables are made up of 60 cords of 6 inches in diameter each, except the last couple of m in length, consisting of only 45 cords.

A more conventional, less costly bridge would be built over the river. For example, the lighting on the bridge is provided by low-level luminaries, rather than lampposts, which would vie with the pylon for dominance of the vertical plane. There is a pedestrian zone, in this case, a central area separated from the movement of vehicles.

The pylon is filled with concrete and acts as a counterbalance for the 35,5 meter ft wide bridge deck, which is anchored by just thirteen pairs of cables. Alamillo is one of six bridges built for the Exposition, but is by far the most memorable. Backfill part of the river 3.

This bridge represented the soaring aspirations of the city of Seville in preparation for Expo ’92and is visible from the top of Gridge Giraldathe former minaret which is the sentimental roof of the city, linking Seville’s past and present. Of all the new bridges that were planned for Expo ’92, the design for the new Alamillo Bridge, planned just north of the expo site, alamilko the most eye-catching.

Erect the steel box girder using the temporary suports.

The smooth surface of the spar is painted matt white, giving a crisp appearance. The bridge has provision for both pedestrian and vehicular traffic. Because of the unconventional structural design and the short period of time available for construction, the building sequence alwmillo also quite different from the standard construction methods used in cable-stayed bridges, where, normally, the first step is the construction of the tower.

Bridfe the implementation of this project by Santiago Calatrava, achieved the following objectives:. Access is by a staircase inside the core of the mast. 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.

The originality of the design lies in the fact the load borne by the cables supporting the deck over the river is compensated not by traditional back stays but by the considerable backward inclination of a massive reinforced concrete tower, so that the resultant of its self-weight, composed alamillk the resultant of the stay forces, follows the direction of the tower. Architecture is better explained in images Follow us on Instagram! The most successful structural forms are often those informed by nature.

The pylon supports the bridgeway with thirteen pairs of cables. It was intended to erect segments of the bridge deck and the tower so that they balanced – so as the deck grew outwards from the tower so the tower grew upwards.

Description With the bridve of this project by Santiago Calatrava, achieved the following objectives: The proof is that the cables that support the bridge are not tight at the top of the mast, contrary to what one would expect.

There are two ways of avoiding this — using a single plane of cables, or arranging the cables in harp form.

Construct the foundations and the lower concrete part of the tower.
