In the seismic design of bridges and building structures, the selection of materials directly affects the safety and stability of the structures. Phenolic silicone rubber, due to its unique performance advantages, has become one of the important materials for enhancing seismic resistance. 
Phenolic silicone rubber introduces phenyl groups into its molecular structure, making it possess excellent high and low temperature resistance, aging resistance, and high elasticity. Compared to ordinary rubber, it can still maintain stable performance within the temperature range of -60°C to 200°C, adapting to the climate conditions of different regions, which is crucial for outdoor bridges and building structures. 
In bridge seismic resistance, phenolic silicone rubber is mainly used to make seismic bearings and expansion joint devices. During an earthquake, the bearing needs to withstand the horizontal displacement and vertical load of the upper structure of the bridge. The high elasticity of phenolic silicone rubber can effectively absorb and dissipate seismic energy, reducing the impact of the earthquake on the main body of the bridge. Its good deformation recovery ability enables the bridge bearing to quickly reset after the earthquake, reducing structural damage. 
In building structures, phenolic silicone rubber is often used as a damping element in key parts such as beam-column joints and curtain wall connections. It can buffer the vibration waves generated by earthquakes through its own elastic deformation, avoiding structural cracking or collapse caused by stress concentration. At the same time, its excellent aging resistance ensures that the damping elements can function stably for a long time, extending the service life of the building. 
With the development of seismic technology, the application of phenolic silicone rubber in the fields of bridges and buildings will be more extensive, providing a more reliable guarantee for structural safety.
