The evolution of neoprene bridge bearings has revolutionized bridge engineering, offering more durable, flexible, and efficient solutions for critical infrastructure. In this article, we explore the latest technological innovations transforming the construction sector.
What Are Neoprene Bridge Bearings and Why Are They Essential?
Neoprene bearings are structural elements designed to absorb movements and distribute loads in bridges and similar structures. Their composition of synthetic rubber reinforced with steel plates gives them unique elasticity and resistance properties that make them indispensable in modern engineering.
Main Functions:
- Movement absorption: Expansion, contraction, and vibrations
- Load distribution: Uniform weight transfer to substructures
- Seismic isolation: Earthquake protection
- Stress reduction: Minimization of structural tensions
Technological Innovations in Neoprene Bearings
