Fasteners in Bridge Structures

Bridge-construction

Bridges are complex systems composed of multiple materials such as steel structures, concrete, and cables.

Fasteners perform critical functions in bridges for connection, load-bearing, and protection:

  • Structural connections: securely connecting steel beams, columns, and supports;
  • Load-bearing and shear resistance: withstanding bridge deck loads and wind-induced vibrations;
  • Corrosion protection: protecting against humidity, salt spray, and temperature fluctuations.
