Bridges

Definition

In the context of mechanical systems, bridges refer to structures that support loads while allowing for movement or transfer of energy, often seen in the design and implementation of vibration control methods. They play a critical role in connecting different elements, enabling semi-active control strategies and tuned mass dampers to effectively reduce vibrations and enhance stability in structures like buildings and bridges.
