High damping isolation rubber bearings for highway bridges

        Isolation rubber bearings not only have all the performance of plate bearings, but also have good isolation performance, which can effectively reduce the damage caused by earthquakes to bridges. High damping rubber bearing is a type of seismic isolation rubber bearing, which is made of high damping rubber material and can achieve a damping ratio of 10% to 16%. Its shape and structure are the same as natural rubber bearings, but its rubber material has high viscosity, can absorb energy on its own, has great ductility, can extend the natural vibration period of the structure during earthquakes, reduce seismic forces, and use its energy dissipation characteristics to exert seismic isolation effect, achieving the performance of lead core laminated rubber bearings.
