Steel Truss Bridge Iron Truss Steel Box Girder Bridge Warren Truss Bridge

Heavy 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.

Advantages

Strong rigidity,Light weight, long crossing capacity.

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.
