Steel structures, such as those used in buildings, bridges, and industrial facilities, undergo a series of processing steps to transform raw steel materials into the final assembled components.
According to the bridge floor position, steel truss bridges are classified as:
- Upper bearing steel truss bridge - bridge floor located in the upper part of the main truss
- Lower bearing steel truss bridge - bridge floor located in the lower part of the main truss
The primary load-bearing structure that supports vertical loads. Composed of:
- Upper chord
- Lower chord
- Belly rod (divided into diagonal bar and vertical bar)
Nodes are classified as large or small nodes, with pitch referring to the distance between nodes.
Classification and functions:
- Longitudinal connection: Upper and lower horizontal systems that withstand transverse loads including wind and centrifugal forces
- Transverse connection: Bridge frame and crosslink that enhance torsional stiffness and adjust force distribution
Composed of longitudinal beams, beams, and their connections. Force transmission path:
- Load acts on longitudinal beam
- Transferred to beam
- Finally transferred to main truss
The surface for vehicles and pedestrians, with forms similar to steel beam bridges and combined beam bridges.
- Large span capability
- Fast construction speed
- Energy efficient
- Aesthetically pleasing
- Excellent seismic performance
