Lead rubber bearings are composed of composite rubber layers, steel plates, lead core rods, etc., laminated and bonded together. The damping is increased through the yield of the lead core, and the horizontal displacement capacity and reset function provide low lateral stiffness to extend the structural period, reduce the peak seismic effect, thereby protecting bridge or building structures from damage and destruction caused by sudden loads such as earthquakes and strong wind loads. At the same time, after an earthquake, the structure can automatically and accurately reset with the elastic force of the rubber material of the bearing, and the bearing can continue to be used. Therefore, lead rubber bearings are a seismic isolation device that integrates support and energy dissipation, and can be used alone. This type of bearing can be used in seismic isolation systems for bridge structures, ensuring that the entire bridge is in a fully and jointly stressed state, thereby improving the dynamic response of the entire bridge and ensuring the reliable stress and structural safety of the entire bridge.
