Long Span Galvanized Surface Treatment Steel Truss Bridge Modern Structural Outlooking

Description

Typically, a steel truss bridge was constructed using a series of triangular-shaped sections of steel that had been riveted, bolted or welded together. The superstructure consisted of two parallel trusses, one on each side of the roadway. Each typically consisted of a chord extending longitudinally along the top of the truss and another chord extending along the bottom of the truss. While many top chords on truss bridges were seen in a “flat” vertical alignment, other truss bridges had a “polygonal” shape vertical alignment. In between the top and bottom chords were vertical and/or diagonal members. The point where the diagonal members intersected along the bottom chord was called a “panel point.”

Specification

The steel truss girder bridge is composed of truss members. Although the steel truss girder bridge is mainly bent and sheared, the truss members are mainly subjected to axial forces.

Application

Generally used for urban bridges or highway viaducts and overpasses with small spans
Reinforced concrete: medium and small span
Prestressed reinforced concrete: large span
Straight leg frame (door type) and slant leg frame: medium and small span
T-shaped rigid frame, continuous rigid frame: large span

Stress characteristics
(1) The piers and columns are rigidly connected, and the beams are unloaded due to the bending resistance of the piers. The whole system is a compression-bending structure and also has a thrust structure.
(2) The clearance under the bridge of the steel truss bridge is larger than that of the arch bridge, and a smaller span can be constructed under the same clearance requirements.
(3) The construction of steel truss bridges is more complicated, and is generally used for overpass bridges and overpasses in cities or highways with small spans.
(4) Steel truss bridges constructed with prestressed concrete and cantilever construction have become one of the competition schemes for long-span bridges.

Our company

Our experienced team is focused on your steel bridge project's success, from start to finish. Our proven ability to identify and overcome design inconsistencies, potential problems with erection, and shipping obstacles results in the fabrication of structural steel that is right the first time, helping you avoid costly construction delays.

Proper project coordination and efficient delivery of the structural steel to your bridge project is a key factor in its ultimate success. This is what gives us the leading edge.

From material purchase and tracing, planning compilation, drawing detailing, production arrangement, quality inspection, to on-going painting, packing and delivering, we have separated department to strictly control process, quality and traceability, so that the perfect Bailey/Belay/Baley Bridge can be made.

Finally we would like to emphasize that not like other companies, nearly all machining parts and mechanical accessories are manufactured in our own shop as we have so many wonderful machines and workers inside. In this way, the quality, cost and delivery time can be ensured which eliminates other exterior factors’ influence.
