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. As in almost all the work of Calatrava, there is some controversy over the work, in particular concerning its structure. There is an excellent balance between light and dark, and the deck itself appears as a particularly slender element. Striking Bridge with Elegance The Alamillo Bridge is a clear example of an unconventional long-span cable-styled bridge; its structural configuration has never been attempted before.
It was ensured bridgee Thanks to this design there is no support needed at the back of the pylon, which results in a more elegant bridge. Accelerate your learning curve by reading stories with Jazyka new, free to use language app!
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.
The La Cartuja Viaduct, 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.
Calatrava provided a fresh take on the idea with the Puente de la Mujer in Buenos Aires, a bridge that opens to river traffic.
Unfortunately this only works for one set of external forces on the bridge and to achieve this balance they have to be known quite precisely. See bridgs pictures 23, 28 Piled: In this platform, metal ribs briddge some 4 meters on both sides, which rests on a slab of concrete that functions as the road; there are two roads of three lanes each.
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 of the resultant of the stay forces, follows the direction of the tower. Technically the bridge is a way of taking forces from up in the air down to the ground.
This is achieved by the steep angle of the cantilever beams that cast the under deck into shadow. They realised that xlamillo must also allow for creep and shrinkage of the concrete in the tower. After that, and by means of the support in the tower provided by the stays, the deck is constructed simultaneously using cantilever method.
Alamillo has a very sculptural form, and this design simplicity gives it order. The right hand diagram is a sketch showing the way the trusses are connected to alsmillo steel outer plate. In other words they act together as one beam because the horizontal shear force between them is resisted by shear connectors Click on the image of the deck cross section above to open a larger version in a new window Cables: The cable stayed cantilever spar concept has been since been replicated, both by Calatrava and others, and is now an established, if expensive, form of bridge construction.
One bridge would cross alamill Guadalquivir and the other would span the Meandro de San Jeronimo near the city of Seville. The box girder and cantilevered road deck elements were initially constructed alajillo continuous falsework, supported on the mostly dry river bed. Alamlilo proof is that the cables that support the bridge are not tight at the top of the mast, contrary to what one would expect. The most successful structural forms are often those informed by nature.
Alamillo Bridge, Seville
One of the largest cranes in the world at the time was required to build the bridge, able to lift metric tons to meters high. Similar to the Brooklyn Bridge, there is an elevated walkway for pedestrians. The Alamillo Bridge is a clear example of an unconventional long-span cable-styled bridge; its structural configuration has never been attempted before.
Mast and bridge deck are embedded in a solid base of concrete, anchored by 54 pillars of 2 m in diameter and 48 m deep.
Materials Mast The mas is made of hexagonal plates of steel, reinforced inside by reinforced concrete. Construction of the bridge began in and was completed in from a design by Santiago Calatrava. The bridge has provision for both pedestrian and vehicular traffic. The basic aesthetic downfall of many cable-stayed bridges is that the design only almaillo in elevation and from oblique angles the cables crisscross and simplicity is lost.
