Bridge bearing pads are a critical component of any bridge structure, providing support and load distribution between the bridge deck and substructure. These pads play a vital role in ensuring the safety and longevity of the bridge.
Material Type | Load Capacity | Durability |
---|---|---|
Elastomeric | Low to high | Excellent |
Metallic | High | Good |
PTFE | Low to medium | Very good |
Type of Bearing Pad | Application | Advantages |
---|---|---|
Elastomeric Pad | Common in highway bridges | Cost-effective, high load capacity |
Metallic Pad | Suitable for heavy-duty bridges | High strength, low maintenance |
PTFE Pad | Ideal for bridges with large temperature variations | Low friction, self-lubricating |
Case Study 1: The Golden Gate Bridge
The Golden Gate Bridge in San Francisco, USA, utilizes bridge bearing pads made of a blend of natural rubber and synthetic fiber. These pads have been in service for over 80 years and have successfully withstood earthquakes, windstorms, and heavy traffic.
Case Study 2: The Millau Viaduct
The Millau Viaduct in France, known for its spectacular cable-stayed design, employs bridge bearing pads made of a high-performance polymer composite. These pads provide exceptional vibration damping and have allowed the bridge to operate smoothly under high wind loads.
