Fast-Installed Steel Truss Bridge with Quick Delivery
The steel truss bridge utilizes a framework of interconnected steel bars arranged in triangular patterns, providing exceptional strength and stiffness. This design offers superior load-bearing capacity, durability, and versatility for various applications.
Design Comparison
Pratt Truss Bridge: Features vertical members and diagonals sloping toward the center span. Vertical members provide compression support while diagonals handle tension, creating a regular, rectilinear appearance ideal for medium-to-long spans.
Warren Truss Bridge: Composed of equilateral triangles, offering a simpler design with fewer members compared to Pratt truss configurations.
Structural Components
Main Girder: Primary load-bearing structure composed of upper chord, lower chord, and belly rod (including diagonal and vertical bars). Nodes are categorized as large or small with defined pitch distances.
Bracing System:
- Longitudinal and horizontal connections stabilize the structure against lateral loads
- Upper and lower horizontal systems withstand transverse forces including wind and centrifugal effects
- Transverse connections enhance torsional stiffness and distribute forces evenly
Bridge Deck System: Comprises longitudinal beams, cross beams, and their connections, efficiently transferring loads from the deck to the main truss structure.
Main Truss Categories
Triangular Truss: Simple design with fixed configuration, facilitating easy manufacturing and installation.
Diagonal Bar Truss: Features multiple bar specifications with significant vertical rod internal forces and large node connections.
K-Shaped Truss: Distributes shear forces across two diagonal rods, creating shorter sections ideal for mounting/dismounting bridges. Complex structure best suited for small-to-medium spans.
Double-Vented Bar Truss: Excellent for large spans with short compression rods that enhance buckling stability. Features simplified joint plate connections.
Applications
- Highway and road bridges accommodating various span lengths and terrains
- Pedestrian walkways and crossings
- Railway bridges requiring heavy load capacity
Common Bridge Types
Pratt Truss: Efficient for medium-to-long spans with diagonals in compression and verticals in tension, ideal for highway and railway bridges.
Howe Truss: Features reversed diagonal orientation (sloping outward) with vertical compression members, historically significant for 19th-century railway bridges.
