Steel Truss Bridge Description:

Fast-Installed Steel Truss Bridge Fast Delivery
Introduction of the steel truss bridge:
 

The steel truss bridge is a type of bridge that utilizes a framework of steel trusses to support the bridge deck. Trusses are structural elements consisting of interconnected bars or beams arranged in a triangular pattern, which provides excellent strength and stiffness. Steel truss bridges are popular due to their strength, durability, and versatility.
 
According to the different position of the bridge floor, it is divided into upper bearing steel truss bridge that the bridge floor is located in the upper part of the main truss and lower bearing steel truss bridge which the bridge floor is located in the lower part of the main truss.
 
The structure composition of rigid truss beam bridge: Main girder, Bracing, Bridge deck system, Bridge floor

(1) Main girder
 

It is the main load-bearing structure and bears vertical loads.

The main truss is composed of upper chord, lower chord and belly rod. The belly bar is divided into diagonal bar and vertical bar.

Nodes are divided into large nodes and small nodes.

Pitch refers to the distance between nodes.

 

(2) Bracing

 

1. Classification: longitudinal connection and horizontal connection.
2. Function: Connect the main truss, make the bridge span structure become a stable space structure that can withstand a variety of lateral loads.
3. The longitudinal connection system is divided into upper horizontal longitudinal connection system and lower horizontal longitudinal connection system. The main function is to withstand the transverse horizontal load, transverse wind, lateral rocking force and centrifugal force acting on the bridge span structure. In addition, the transverse support chord, reducing its free length outside the plane.
4. The transverse connection is divided into bridge frame and crosslink. The main function is to increase the torsional stiffness of steel girder. Properly adjust the uneven force of the two main stringer or two longitudinal links.
 
(3) Bridge deck system
 
1. Composition: the longitudinal beam, beam and the connection between the longitudinal beam.
 
2. Way of force transmission: the load first acts on the longitudinal beam, and then from the longitudinal beam to the beam, and then from the beam to the main truss.
 
(4) Bridge deck
 
The bridge deck is the part for vehicles and pedestrians to walk on. The form of the deck is similar to that of steel beam Bridges and combined beam bridges.
 
Geometric characteristics of the main truss:
 
Economy, simple structure, conducive to standardization and easy to manufacture and install.
 
 
The main truss categories:
 
Triangular truss: Triangular truss structure is simple, the design is fixed, easy to install and manufacture.

Diagonal bar truss:
 
Many bar specifications.
Many specifications and large internal force of the vertical rod.
All are large nodes.

The K-shaped truss:
 
The shear force of the same node is borne by two diagonal rods, which are small and short in section.
The bar has many specifications, many nodes, short intersections, and many crossbar beams and connections. For small and medium-sized spans, the structure is complex.
For large spans, the rods are short, light and suitable for mounting and dismounting Bridges.

Double-vented bar truss:
 
The same internode shear force is borne by two diagonal rods, which are small and short in section.
It is used for large span, short compression inclined rod, which is favorable for buckling stability.
The small section of the inclined rod makes the number of connecting pins on the joint plate less, and it is easy to arrange the joint.

Advantages of the steel truss bridge:

 

Large span
Fast construction speed
Energy saving
Beautiful building appearance
Good seismic performance
Wide application
Can be customized
 
 

Application of the steel truss bridge:

 

Highway and Road Bridges: Steel truss bridges are frequently used in the construction of highway and road bridges. They are suitable for a wide range of span lengths, from short to long, making them versatile for accommodating different road widths and crossing various terrains.
