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
