Summary of Entries to the European Steel Bridges Award 2010

Description: The viaduct constructed between 2007 and 2009. The deck, 200 meters long by 20,1 meters wide, is a mixed steel/reinforced concrete structure. The steel framing is formed by a pair of longitudinal box girders having a height just above one meter by two meters in width, spaced out at 8 meter centres. The longitudinal box girders are connected between each other and stiffened with “T” sections spaced out at circa 4 meter centres. The box girders also form a surface for supporting the pre-cast deck elements necessary for casting the reinforced concrete deck. The arch, which develops overa length of approximately 170 meters, is formed from a steel box girder of varying height with continuità from the abutment, where the height is greater than 5 meters and the mean width circa 2,6 meters, up to the arch ridge, where the box flattens out and becomes 1 meter high by 10 meters wide.
Total tonnage: 2000 t

Description: The bridge is divided into two immobile parts and the movable swing bridge, which is disconnected from the overall system when opened.
The three parts of the supporting structure are connected by lock bolts when the bridge is closed. Accordingly, the supporting structure is composed of changing components. When open, the bridge comprises three subsystems: one two-span beam with spans of 2 x 21 m, one balanced double cantilever with spans of 2 x 20.5 m, and one single-span beam with a span of 17 m. When the bridge is closed, its supporting structure is a continuous beam across 5 spans of 21.0 m / 21.0 m / 22.7 m / 21.3 m / 17.0 m. The middle support at the pivot is a steel column with a pipe cross section approx. 2 m in diameter and a ball bearing with gear ring at the intersection of the bridge's superstructure and the column head.
Total tonnage: 300 t

Description: The deck has an overall length of 67.70 m. It has 2 spans of 49 m and 18 m. The structure consists of a mixed steel / concrete double beam of variable height.
The height of the girders varies from 0.80 m to 1.75 m abutment on the central support. The upper soles have a thickness of between 25mm on abutments and 55 mm on pile. The width of the soles is 0.40 m. The cores have a thickness ranging from 1.2 cm to 1.6 cm on supports. A prefabricated reinforced concrete slab of 12 cm thickness is bonded to the metal frame via connectors. The structure is equipped with stainless steel braces supporting the slab underside, lighting poles and curved steel guard rails, which provide the necessary safety whilst giving a light appearance to the bridge. Calculation and drawings: 3 months, manufacture: 4 months, assembly over the Blavet river: 2 months

Description: For the bridge across the “Neue Fahrt” an effective span of the clamped construction of 46.00 m at a length of ca. 56.20 m is reached. It is built as a composite construction, consisting of a deck of reinforced concrete and steel beams of alternating height, at intervals of about 2.50m. The longitudinal beams are supported by arched cross beams.
For the bridge an effective span of the clamped construction is of 68,20 m, in three single spans of 13,60 m, 19,40 m and 30,30 m.
The normal section for the bridges is characterized on one hand by the row of trusses in longitudinal direction and on the other by the combined structure consisting of steel trusses and the bridge deck in reinforced concrete.

Description:The bridge have been designed and built in balance with very specific historical place. The new connection of 2 divided parts of town raised the comfort of pedestrians and cyclists, separating them from heavy road traffic.The bridge has 2 symmetrical pylons, diverted from the river. The pylons are shaped in dynamic style, with changing width from bottom to top and cross sections changing along the height. Composite pylons are formed of steel box sections, filled with structural concrete. The deck is steel, formed of rolled H and U sections. Main girders are H400B, cross girders are H300B. Cross girders are supported by suspension, in distance 2,45 m. Main suspension cables as well as opposite cables are 31Ø15,3 – 1680/1860 with plastic sheet and damping device in anchor. The cables for central span and opposite cables for counter-force are separate, anchored at the pylon head. The deck is suspended by steel rods Ø30 with special links, enabling rotation. Structure dimensions: Length: 109,40 m; Main span: 89,40 m; Pavement width: 4,0 m; Traffic: pedestrians and cyclists, possibly ambulance; Pylon height: 13,60 m
Weight of steel: Deck: 73,9 t; Pylons: 77 t

Description: The new supporting structure is made from steel, with lattice main girders of the oblique non-vertical system with the top orthotropic bridge floor.
The new bridge has the following characteristic:
Bridge span: 49.95 + 59.94 + 59.94 + 49.95 m Steel structure length: 220.97 m
Bridge height: 48.9 m
Free width on the bridge: 6.27 m
Bridge structure clearance: MPP 3.0
Structural height: 5.73 m
Supporting structure weight: 1011 t

Description: The structure is formed by 9 spans up to 80 m long, with a total length of 565 m. The total width of the deck is 14,5 m, with 3 traffic lanes. The cross section of the deck consists in a steel girder box (S355 J2G3) of variable depth in the first six longer spans, and constant depth in the last three shorter ones. The depth varies between 3,85 m at the piers to a minimum of 1,75m at mid-span. This depth is kept constant for the last and smaller spans. On both sides of the deck, steel ribs are disposed every 4,0 m, supporting the 3,5 long cantilevers. These ribs are defined continuous between the girder’s webs, creating a both longitudinal and transversal composite behaviour for the structure. This fact reduces the concrete slab thickness to only 0,25 m.
Total tonnage: 1916 t

Description: In this project, a technical and human approach is essential, and several factors are relevant: the aesthetics, the type of construction, the economics and the adaptation to the environment.
The bridge crosses a 28 m long channel, with a 5,0 m wide platform. This platform includes 3,0m m for pedestrian use, and 2,0 m for the bicycle lane. The different usage is subtly marked on the floor, with a line of embedded lighting.
The structural outline is clear and conceptually very simple: two Vierendeel trusses which function as a guardrail and where the lateral lighting and handrail is integrated. Pure simplicity.
Transversally, the bridge has an I-beam every 1,00m. All these beams are GFRP, except four of them, where stainless steel is used. These beams support the GFRP panels that constitute the transit platform for the footbridge. These panels have a anti-sliding finish, based on a layer of sand with epoxy resin.
Total tonnage: 25 t

Description: The two edges connected by the new bridge have different height. The side of the commercial area is more than 6m higher than the N-141c and the sidewalk on the other edge near the residential area. To cross the road with a minimum vertical clearance of 5.5m the access on the residential side has been solved by means of an elevator and stairs. The main structure consists of an asymmetrical arch and a medium deck connected by stays. The arch, with a span of 40m, has a triangular section, almost equilateral, only 0.45m high, and it’s tilted in plan and elevation, although in one single plan, forming 28º with the vertical.
The deck consists of a longitudinal trapezoidal box and ribs. The box has a width of 1.60m, with constant longitudinal depth. Transversely, the section is a trapezoid, almost triangular, with a depth variable between 0.15 and 0.60m. From the less deep side come out the ribs that have a length of 1.40m and variable depth between 0.15 and 0.09m. This provides a deck with a free width of 3m.
Total tonnage: 33 t

Description: The general design of the footbridge has been strongly conditioned by the presence of
the existing bridge, and it was necessary to line up the new abutments and piers with the existing ones for hydraulic purposes, hence the rhythm of the new supports had to follow that of the old ones. For this reason, like the old structure, it is a four equal 22.9
metre span, resulting in a 91.6 metre long continuous structure.

Description: The structure of the bridge is composed of four main structural elements: the box, the upper chords, the façade and the ribs.
The steel box of curvilinear plan has a variable width between 12.00 m and 29.00 m and a variable depth between 3.30 m y 5.55 m. For architectural reasons, its exterior is covered with a 6 cm thick shotcrete layer. There are diaphragms placed inside at every 3.60 m. The upper steel chords are placed on each one of the three modules. The ribs as well as the inner diaphragms of the box are based on parallel plans at 3.60 m from each other and delimit every single module. The façade is composed of panels put between every two ribs in the longitudinal direction. Each panel consists of two orthogonal groups of rectangular steel profiles of 160 x 80 mm.

Description: The viaduct is composed of a box girder edge 750 mm by 550 mm wide, resting on circular columns of 508 mm in diameter whose separation varies between 9 and 32.5 m. The layout of this sort of bridge allows a comfortable route, avoiding some interference with urban obstacles. Above this beam circulates a tram-car capable of carrying 36 people + 2 PMR. The displacement of the rail vehicle is done through support of tires on the upper surface and side tires to stabilize the vehicle. The box girder is composed of plates 10, 15 and 20 mm thick. The steel used is S355 J2.
Total tonnage: 220 t

Description: The original bascule bridge was transformed into a new swing bridge. The original bascule bridge, spanning 98 m and with an 8 m wide platform for rail and road use, was designed in 2001. Both moveable cantilevers spanned 49.0 m and the counterweight arms spanned 13.5 m, resulting in a total length of 125 m (62.5 m long each bascule leaf). The new bridge spans 99.2 m. The overall width of the bridge is 20.45 m and the road width between main longitudinal beams is 18 m. This new road width largely doubles that of the original bridge (8 m) and underlines the complexity of the transformation.

Description: The bridge, designed for foot and cycle traffic only, is above high-water level. The defined position of the crossing results in a span of 42.00 m. The clear, usable width between the parapets is 3.00 m.
Particular attention was given to designing the details of the bridge, which are crucial to its durability. The bridge deck consists of two steel 350 x 350 mm hollow sections running the full length of the bridge. They are positioned 4.00 m apart and also turned through 45° to create a diamond-type cross-section. These two main members are connected at regular intervals by transverse hollow sections to form a grillage.
The bridge deck itself is just 475 mm deep. It is supported above the river by five tie rods in an asymmetric arrangement which connect the bridge back to the approx. 25 m long steel pylon leaning out over the water.

Description: The new suspension bridge crosses the Rhein-Herne Canal in a broad gesture. The curved steel superstructure with a main span of 141m is suspended on the outer edge of the cross section by a cable structure fixed to a 45 m high mast at the northern bank. The main cables are anchored tangentially in the deck roughly 24 m before the abutments: the connection does not have additional support. 30 stainless steel hanger cables every 3 m are connected to the main suspension cables by machined clamps. In order to reduce the length of the central hanger cables, a secondary, garland-shaped suspension cable runs between the main suspension cables at midspan.

Description: For each platform served, the bridge is equipped with a glazed lift and a staircase measuring two dimensional units.
The fl ights of stairs are at least 1m40 in width and the deck is 2m wide. The lifts have a 630kg capacity and are accessible for people with reduced mobility. In order to minimise turnaround times, the lifts are designed for dual service, ie, car ingress and egress are directly opposite, which means users always walk forward when entering or leaving.
Vertical travel is variable, depending on the site, but is never greater than 6m50.

Description: The bridge was designed as a hybrid structure, with a structural FSC-certfied timber deck, supported by a slender steel arch. The primary structure consists of steel arches with a span of 62.3m. These are created from bent circular tubes bent oriented in vertically inclined planes. The steel struts, V-shaped steel tubes rigidly attached to the arches, support the deck and create a half beam Vierendeel truss. Detailed geometric studies were carried out for the bridge’s steel castings, which connect the various elements of the structure, anchor the structure to its abutments and give it a manufactured character. The castings were also the focus of meticulous coordination efforts with the constructor to find the best erection technique. Designing with steel creates opportunities for very light structures that span long distances. Total length 80 meters, mais span 65 meters.
Total tonnage: 70 t

Description: The bridge is a Calatrava designed, cable-stayed, steel box girder structure, with a span, across the river Liffey, of 123 metres. The bridge, which rotates through 90 degrees, has an asymmetric shape, with the base to the cable-stayed steel pylon set, outside of the river’s navigational channel - 28 metres from the river’s South quay wall; the pylon curves northwards to a point 48 metres above the water level with 25 forestay cables set in a ‘harp’ formation. The bridge deck is a steel box girder with stiffened plate cantilever sections fitted to either side of the box girder. The thickness of the plates in the structure range from 10mm for the cantilever deck up to 180mm for the backstay anchorage plate at the tip of the pylon. There are 25 forestay cables of 60mm diameter and 6 backstay cables of 145mm diameter.

Description: The aim was to create a very gentle bridge construction which leads the visitors through the very last extensions of the famed Vienna Wood. The site for the trail was carefully chosen to ensure that plant and animal communities were not disturbed during the building of the bridge. Moreover, the construction itself should not interfere with the natural habitat of native plants and animals, but be a part of its natural surroundings.
The entire structure has a length of approx. 150 m and is formed by 3 suspension spans with
different lengths. The spans are about: span 1: 67m + span 2: 44m + span 3: 40m
The spans are connected by pylons with a height of up to 16,5 m. Each pylon carries a platform with an area of about 25 m².

Description: 104 years after being built, the railway bridge across the Danube at Tulln has been completely reconstructed. The new bridge is based on a composite truss construction. The basic idea of the assembly method, which has been developed by MCE, was to construct two 182 m long bridge sections with a weight of 1.550 t. The two bridge sections were assembled like an incremental launching method parallel to the river Danube. Each of these two parts was floating with a heavy-duty pontoon in his final position. For the dismantling of the existing supporting structure and the assembly of the new one incl. the railway facilities, the railway line was blocked for 7 months. After a construction time of only 16 months, commissioning in October 2009 was the last step in a project that will make European bridge construction history.
