Self-reset after earthquake.
The vibration period has nothing to do with the carried mass.
As a widely recognized and effective type of seismic isolators, the friction pendulum system plays a crucial role in modern structural engineering. Friction pendulum isolators are primarily utilized in the design and implementation of friction pendulum bearing isolators, which are essential for enhancing the seismic resilience of buildings, bridges, and other critical civil structures. These isolators are not only integral to new construction projects but also serve as a key component in the seismic reinforcement and renovation of existing infrastructures. By incorporating friction pendulum isolators, engineers can significantly reduce seismic forces transmitted to the structure, thereby ensuring greater safety and longevity. This advanced technology is indispensable for achieving optimal performance in seismic-prone areas, making it a preferred choice for engineers and architects committed to safeguarding their projects against earthquake damage.
