1. Vibration Reduction: They help reduce the vibrations caused by various factors such as wind, traffic loads, and seismic events. This is important because excessive vibrations can lead to structural fatigue and damage over time.

2. Improved Comfort and Safety:By reducing vibrations, bridge dampers improve the comfort and safety of vehicles and pedestrians using the bridge. Reduced vibrations can also enhance the lifespan of bridge components.

3. Seismic Resilience: In areas prone to earthquakes, bridge dampers play a significant role in enhancing the seismic resilience of bridges. They can absorb and dissipate energy during seismic events, helping to prevent catastrophic failure.

4. Cost Savings: While installing bridge dampers adds to the initial construction cost, they can lead to long-term cost savings by extending the lifespan of the bridge and reducing maintenance and repair expenses caused by excessive vibrations.

Overall, bridge dampers are essential for ensuring the structural integrity, safety, and longevity of bridges, especially in areas with high traffic or seismic activity.
