MOVABLE BRIDGES—

Waagner-Biro offers the complete range of movable bridges. Whether in Istanbul or in Hamburg - we keep the traffic flowing!

In cities, where space is limited for conventional bridges, bascule bridges offer a solution for the crossing of road traffic and waterways. Single-leaf bascule bridges and symmetrical bascule bridges with two leaves and an opening angle of up to 85° allow ships to pass through without any height restriction. Bascule bridges are especially suitable for shipping channels located close to the coastli-ne, where amongst the coastal shipping large sea

going vessels also tend to operate. In order to faci-litate the construction of the moving parts, the bridge leaves with the carriageways for road and rail traffic are usually made from steel. At present, the electro-hydraulic drive with hydraulic cylin-ders represents the most cost-effective driving mechanism and guarantees maximum availability with low maintenance costs. The necessary lo-cking mechanisms in the centre and at the ends of

the bridge are also hydraulically driven. The ope-ning time of 90 to 180 seconds is shorter than the time needed for managing road and shipping traf-fic.

BASCULE BRIDGES


SWING BRIDGES

Swing bridges are particularly suitable for bridging inland navigation channels where elevated road or railway bridges seem impractical for economic and town planning reasons.

For the bridging of larger navigation channels it can be an advantage to combine swing bridges with fixed bridges. In such cases a higher carriageway is chosen for the entire bridge so that the clearance height is sufficient for normal ships and the bridge needs to be opened for large ships only. In most cases swing bridges are designed as a symmetrical construction with a central column, so that two shipping channels with unlimited clearance height are available on each side of the central column.

Proven driving systems are available for the central pivot bearing and locking at the outer ends. In the past, rolling slewing bearings were used to support vertical loads. For taking today’s heavier vertical weights, Waagner-Biro has developed a special combination of hydraulic lifting and turning cylinders. The latter are connected to the centre pivot for slewing the structure. Special bearing rings consis-ting of bronze segments were developed for stabilisation of particularly heavy bridges. Tailor-made locking and emer-gency systems increase the operational availability of the bridge.

VERTICAL LIFTING BRIDGES

As yet, the classic vertical lift bridge has been used in urban settings to bridge inland shipping lanes. However, the clearance height for ship-ping remains limited.

The supporting construction of the bridge con-sists of steel, in order to reduce the weight to be raised and to allow a cost-effective configurati-on of the lifting unit. The bridge is connected to the counterweights by support cables which are usually arranged at the four corners. The weight of the bridge support is therefore largely balanced out and the remaining load is raised and lowered by means of cable winches.

SPECIAL BRIDGES—SUSPENSION BRIDGES

Suspension bridges are used for the largest spans. The cost-effective range of use is for spans between 300m and 1,500m. In specific cases the construction of smaller suspension bridges of less than 300m would be appropria-te. One can also build smaller bridges with spans of approx. 100m.

The construction consists of two support tow-ers, to which main support cables are fastened on both sides. On the suspension cables, high strength hangers are mounted, which hold the carriageway and the main girder beneath them. Tractive forces occur on the cables, which must not only take up the entire load of the traffic and of the supporting structure itself, but also the dynamic wind and earthquake loads, which are especially relevant for suspension bridges. The pressure loads that occur are diverted into the bottom chord via the towers.

CABLE STAYED BRIDGES

Cable-stayed bridges consist of one or several pylons, from which slanting stay cables support the main deck. The span of cable-stayed bridges ranges on average between 100m and 500m. Two major types of cable arrangements have proven to be effective: In the fan-shaped design the cables are connected to the top of the tower, in which case every stay cable is anchored in the main span, runs over the tower saddle and is anchored in the span section behind. Alter-natively, in the harp-shaped design, the cables running from the deck to the tower are practi-cally parallel to each other, as a result of which they are spread out evenly along the height of the tower.

As with suspension bridges, it is particularly important to protect cable-stayed bridges against oscillations caused by wind. Due to the aerodynamically favourable form of the bridge cross-section and cable, a stable construction can be achieved. The pylons are constructed in many different shapes, which are also adapted to the foundation conditions (e.g. A-pylon, Y-pylon, centre pylon, two pylons).

Donaustadt Bridge, Vienna, Austria

Supporting structures in the form of suspension bridges are commonly used to bridge the gap over large rivers or valleys for oil or gas lines, conveyor belts, water pipes or drainage channels. Back in the 1960s, Waagner-Biro developed a unique carrying system of Y-shaped pylons with three cables inclined spatially towards each other for better stabilisation of the pipeline bridges. The system is characterised by two oblique bea-ring walls arranged in a V shape, supplemented by a central pre-tensioning cable running along the tube route and curving upwards.

The essential element of the construction is the central nodal point. It joins the support and pre-tensioning cables in the middle of the bridge and thus contributes to the rigidity under a partial load – otherwise a weak point with this kind of suspension bridge system. The construction is also suitable for pedestrian traffic. The slender and yet compact appearance of the supporting structure is characterised by the two Y-pylons. Waagner-Biro has already completed a high number of these supporting structures with open spans of over 300m.

Bridges with main girders produced as truss constructions have the advantage of relatively low weight, as regards both the construction and the individual parts (truss beams). Bridges of this kind are built for open spans of up to 300m and can be used for roads, railways and other combined applications. Truss bridges can be supplied in bolted or fully welded design.

TRUSS BRIDGESTruss Bridge on Belitung Island, Sumatra, Indonesia

Waagner-Biro has over a 160 years of experi-ence with the construction of truss bridges (truss girders on both sides above the carriage-way) and suspended truss girders (carriageway on the upper chord as well as truss girders below the carriageway).

Pedestrian bridges are used to overcome obsta-cles such as roads with heavy traffic, rivers or railway lines. Waagner-Biro has built numerous pedestrian bridges either as truss girder, arch, cable stay or other types. Claddings and walk-ways are carried out in steel, timber or glass. Architectual lighting of the pedestrian bridge creates another added value.

The fly-over-ramp as a “bridge over the bridge” for the unhindered replacement of expansion joints and/or the carrying-out of repairs has proven itself effective in regular use since 1999.

Many carriageway expansion joints which have been built during the past few decades are like-ly to be severely damaged due to mechanical influences. It is therefore necessary to replace the damaged mechanical constructions with finger expansion joints. Since repairs and the blocking of individual lanes that they entail cause long diversions and major congestion, the idea was born to engineer a ramp under which the necessary work could be carried out without hindering the traffic.

The technicians of Waagner-Biro accepted the challenge and developed the fly-over ramp, which was first used in 1999 at the south-east expressway in Vienna. The required width can be achieved by placing individual elements to-gether. Both length and width of the fly-over ramp can be altered as needed.

Elegance of shape combined with load-bearing function are the main design parameters of arch bridges. Depending on the conditions of the site, the carriageway can be suspended from hangers or arranged on supporting columns above the arch. Arch bridges already played a major role in the early years of Waagner-Biro.

Depending on the characteristics of the site, bridges are built with their arch above the carri-ageway (“suspended“ carriageway), or with their carriageway over and supported by the arch (“elevated“ carriageway).

Arch bridges are cost effective in spans from 100m to 300m, arch bridges constructions for smaller spams are used in particular cases too.

MODULAR BRIDGES—Application / Handling

The bridge units can be assembled with the simplest means by local unskilled workers. The open spans are usually from 35 to 60m with a normal interval increment of 5m. Bridge spans of up to 120m have already been achieved in modular construction. The bridge widths vary between 4m for a single-lane and 7.3m for a two-lane carriageway.

At the customer’s request, multiple-lane modu-lar bridges could be offered as well. The walk-ways have a standard width of approx. 0.7 m. Several individual bridges can easily be com-bined into multiple span bridges. The construc-tion elements of the system bridges are gene-rally supplied galvanised. The carriageways can be made of steel, concrete and/or wood, and fitted with rails. The construction parts are only bolted together at the building site, so that no welding work is necessary. The system bridges can thus be dismantled and rebuilt elsewhere.

The modular bridges from Waagner-Biro are a versatile and extendable building block system individually adaptable to special customer re-quests. Waagner-Biro is among the internatio-nally most renowned providers of system

bridges. The modular concept offers all the ad-vantages of modern bridge construction and an extremely high degree of flexibility as regards bridge width, open span and load - enabling us to meet the customers‘ requirements appli-

The panel bridge from Waagner-Biro constitu-tes a modular bridge system, easily adaptable to different open spans, carriageway widths and traffic loads by varying the arrangement of the panels.

The Waagner-Biro panel bridge uses a single type of panel for all configurations. The panel is made of standard sections welded together to form a truss framework which has a system height of 2.15m and a system length of 3.048m.

The main girders of the bridge are formed by connecting several panels with bolts. Standar-dised cross girders are available in the carriage-way widths of 3.15m, 4.20m and 7.35m.

The carriageway consists of steel elements with a non-slip surface; a wooden covering on longi-tudinal steel girders is an alternative.

Advantages

• Fast availability (stock item)• Extremely short assembly time• Simple to build• Short training of the personnel• Light individual components• Simple adaptation to different open spans, carriageway widths and traffic loads due to modular construction• High load capacity due to extremely strong steels and a system height of 2.15m• Use of one standard panel• Simplification of logistical procedures• Corrosion protection of all parts by hot dip galvanising

THE WORLD‘S STRONGEST PANEL BRIDGE

Standard panel bridge elements can be used to create rapid and economically sound solutions, even for highly specific applications. This is why Waagner-Biro was awarded the contract to erect panel bridges for the transport of heavy loads during the construction of a power stati-on in Algeria.

Rapid delivery and erection of the bridges were essential as the existing bridge infrastructure in Algeria was not designed to take heavy loads of up to 512 tons and - in addition - the delay pe-nalties were an imminent risk as is current prac-tise in the area of power plant contruction.

A combination of standard panels arranged in rows of 3 next to each other and up to 4 panels high ensured that the bridges had the necessary load-bearing capacity.

The panel bridges were erected by incremental launching under the instruction of Waagner-Biro experts. Installation of the longest bridge, which measured 67m, was completed a week faster than the 5-week construction period ag-reed upon in the contract.

Waagner-Biro continues to experience a rising demand in the services and maintenance field in Austria, Central Europe as well as in the Uni-ted Arab Emirates.

In Europe, many steel structures have reached an advanced age leading to a growing need for refurbishing.

In other areas, such as the United Arab Emira-tes, maintenance is carried out to restore equip-ment, machines or systems to a normal operati-onal condition.

So whether it is a simple infrastructure or com-plex mechanical project, Waagner-Biro carries out maintenance, service and refurbishment in accordance with the highest internationally re-quired standards.

Waagner Biro‘s service and maintenance de-partment helps its customers to extend the life of steel structures by offering installation and maintenance services in the fields of steel engi-neering, hydraulic steel engineering, bridge construction, stage equipment and façade con-struction.
