Steel Truss Bridge Temporary Bridge Structures Truss Arch Bridge
Steel truss bridge is a down-through steel truss bridge that can be
used for permanent or semi-permanent bridges. The bridge consists
of the main truss, the deck system, the connection system, the
bridge foundation and the bridge's auxiliary structures. Bridge
decks are generally in the form of reinforced concrete panels and
asphalt concrete paving. Compared with the solid web beam, the
sparse web beam is used to replace the overall web, thereby saving
steel and reducing the weight of the structure. Because the amount
of steel in the web beam is less than that of the solid web beam,
the steel truss can be made larger height, which has greater
rigidity and greater spanning ability.
Introduction
Steel Truss Bridge is a standard bridge equipment, adopted extensively and the most
popular in the world.
Features
1. Steel Truss Bridge is easy to repair and replace,long lifetime,material can be
recycled.
2.Due to the steel isotropic, quality of a material is uniform and
modulus of elasticity, that make steel bridge in the working
condition and calculation compared with the assumption
3.Steel Truss Bridge generally USES factory, site splicing, the construction period is
short, processing convenient and not affected by seasonal effect.
4. Steel Truss Bridge is suitable for industrialized manufacture and very convenient to
transport.
5.High strength and big stiffness , relative to the concrete bridge
can be reduced trabecular high and self-respect
Advantage

Application
Beam bridge,arch bridge,rigid frame bridge,cable-stayed
bridge,suspension bridge. passenger foot-bridge
Mixture form to erect all kinds of
The compact 200 panel bridge: The compact 200 panel bridge is
similar to the compact 100 panel bridge from their appearance. The
difference is its increased panel height to 2.134m. It employed the
method of alternating joints between Reinforcement Chords and the
joints between panels. This method can decrease inelastic
deformation caused by the oversized pinholes.
Bolt-connected components use the orienting sleeve- fixing method
to increase accuracy of connections. Shear is created in orienting
sleeves and tension is developed in bolts, which increase the usage
life of the bolts and ensure the safety of panel bridges. Wind
resistant brace is made to be composite type and is connected to
transom/girders to improve overall stability of panel bridges.
Pre-arch method is used to additionally cut down mid-span and
vertical deflection to a larger degree.
Temporary Bridges, Emergency Bridges and Fixed Bridges.
Using the bridge equipment, the suspension bridges of varied span
can be erected.
The bridge has the advantages of few components, light weight and
low cost.
Bailey Bridge requires no special tools or heavy equipment for
construction, the bridge elements
are small enough to be carried in , and the bridge is strong enough
to carry . It is considered a great example of military
engineering.
