ECCS Awards for steel bridges 2010 >
Photo gallery
The European Convention for Constructional Steelwork organizes the 2nd
ECCS Award For Steel Bridges in 2010.
The objective is to give European recognition to outstanding steel and
composite bridges and footbridges, emphasizing the many advantages of
steel in construction, production, economy and architecture. The Awards
are opened to steel and composite bridges which steel structures were
fabricated in the ECCS full members countries. The construction
must have been completed and be ready for use within the last three years.
Bridges, footbridges and renovation projects (major retrofit, expansion
or rehabilitation) are eligible.
All applications were assessed against the following criteria:
- to be of an internationally recognised standard,
- to be outstanding in its construction,
- to emphasize the advantages of steel in construction, production,
economy and architecture,
- to disseminate the knowledge of steel, its many uses, and to draw
attention to its development,
- to improve the image of steel,
- to interest clients, architects and engineers in using more steel
within the entire building sector,
thereby making the steel industry competitive.

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: 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 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: 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: This bridge is the first structure from a large
program concerning the rehabilitation of a series of historical
bridges. Every case must be separately considered. Nevertheless
the rehabilitation of such representative structures is one of the
main tasks of the bridge engineers. For the deck, the solution of
a composite structure was chosen. The thickness of the new concrete
deck is 22 cm. Headed studs with D=22 mm welded through steel sheets
were used. Bridge with four spans and parabolic main girder L =
4 x 39,8 = 159,20 m
Total tonnage: Initial Structure 422 tones, Strengthening 92 tones
(ca. 0,6 to / m) Total: 514 tones
