Steel Truss Bridge Truss Bridge Construction Temporary Road Bridge
Steel Truss Bridge Truss Bridge Construction Temporary Road 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.
Main technical data
Bridge design span is 40-120m, small span from 40m to 80m, large
span from 80m to 120m. Design load usually be highway-i level, also
can be H25-44 from USA or UK HA +30HB. The carriageway can be
double lane or four lanes.
Advantages
Light weight, long crossing capacity, strong rigidity.
Features
1. Steel Truss Bridge generally USES factory, site splicing, the construction period is
short, processing convenient and not affected by seasonal effect.
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 is suitable for industrialized manufacture and very convenient to
transport.
4. Steel Truss Bridge is easy to repair and replace,long lifetime,material can be
recycled.
5.High strength and big stiffness , relative to the concrete bridge
can be reduced trabecular high and self-respect
Application
Beam bridge,arch bridge,rigid frame bridge,cable-stayed
bridge,suspension bridge. passenger foot-bridge
