Elastic-Plastic Steel Damper Bearing
Product Introduction
The Elastic-Plastic Steel Damper Bearing is a type of bridge bearing that integrates load-bearing and energy-dissipation functions. It utilizes the elastic-plastic deformation of its steel damping components to transmit vertical loads while simultaneously absorbing and dissipating seismic energy, thereby achieving structural seismic resistance and vibration control. Its core working principle involves incorporating elastic-plastic steel damping elements within the bearing. Under normal conditions, these elements remain elastic, transmitting vertical loads and accommodating structural displacements. During an earthquake, the damping elements enter a plastic state, absorbing and dissipating seismic energy through repeated yielding deformation, thus reducing the dynamic response of the structure.
