A total of 13 pairs of cables are used. The bridge has provision for both pedestrian and vehicular traffic. Alamillo has a very sculptural form, and this design simplicity gives it order. Laamillo and bridge deck are embedded in a solid base of concrete, anchored by 54 pillars of bridfe m in diameter and 48 m deep. This is achieved by the steep angle of the cantilever beams that cast the under deck into shadow.

Concrete is strong in compression but weak in tension where it has to be reinforced with steel bars. The pedestrian pathway has a disappointing tarmac finish, but the guard rails that run vridge the bridge have an interesting texture and design. Santiago Calatrava Valls, a Spanish neofuturistic architect, structural engineer, sculptor and painter designed Alamillo Bridge.

Transmit tension and consist of 60 steel strands mostly – the longest stays have 45 each 15 mm. Cantilever spar cable-stayed bridge.

The simplicity of the colour scheme complements the bridge design, leaving its striking form unspoilt. The steel wings, supporting the deck to either side, are cantilevered off this spine, whose 3.

The old course of the river, now a branch of the rerouted river, was renamed Meandro de San Jeronimo. The original intent was to build two symmetrical bridges on either side of the island, but in the end, the Alamillo’s singular design has proved most striking. The pylon supports the bridgeway with thirteen pairs of cables.

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. They realised it was possible to backfill part of the river underneath the bridge and erect temporary supports. In the Alamino Bridge, the construction sequence was completely bridg.


Views Read Edit View history. It is a continuous structure with a vaulted underside and overlapping levels: Iron, carbon with other additives such as chromium etc Concrete: The deck itself flows smoothly over the water, drawing the eye along and up the inclined spar.

Cables The cables are made up of 60 cords of 6 inches in diameter each, except the brldge couple of m in length, consisting of only 45 cords. This bridge represented the soaring aspirations of the city alamilol Seville in preparation for Expo ’92and is visible from the top of La Giraldathe former minaret which is the sentimental roof of the city, linking Seville’s past and present.

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.

J R Casas A combined method for measuring cable forces: Construction of the alammillo and temporary backfill of the river Construction of bidge piers to support the deck elements Construction of the deck over the temporary piers Construction of the lower part of the pylon The rest of the pylon was built in segments and stabilised by the deck and the progressive placement of the stays. The bridge was constructed as part of infrastructure improvements for Expo 92which was held on large banana farms on brkdge island.

This page was last edited on 14 Marchat The design and construction of the Alamillo Bridge provides an insight into one the best Architectural and Engineering minds of our time. In practice this is impossible. The Alamillo site is unusual in that the same river is crossed twice. 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 nridge deck itself cantilevers transversely.

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. The bridge deck is designed as a metal structure and consists of a central platform and hexagonal anchorages where the cables attach. 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 bridgw design bridge deck, the tower and the foundations to cope with very large bending moments.


Alamillo aalamillo one of six bridges built for the Exposition, but is by far the most memorable. Seville Andalusia — Spain.

Aesthetics Alamillo is a beautifully proportioned bridge. Think of a truck standing on the brdge and how its weight is transmitted through the bridge to the ground. The basic aesthetic downfall of many cable-stayed bridges is that the design only works in elevation and from oblique angles the cables criss-cross and simplicity is lost.

Siemens offers integrated solutions for smart city development. Thanks to this btidge there is no support needed at the back of the pylon, which results in a more elegant bridge. See slideshow pictures and Supporting cables: The deck of the bridge, with a m span, is supported every 12m by a pair of stays. They alaamillo that small variations in the weight of the tower and 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 steps of construction are as follows:. Construct temporary piers 4.

Alamillo Bridge

Construct the foundations and the lower concrete part of the tower. The Puente del Alamillo is the only [ citation needed ] bridge that brldge balanced solely through added weights not requiring any type of back anchorage.

Structural Design The inclined pylon of Alamillo had no structural precedent.
