Seismic steel ball bearing steel ball bearing seismic performance is set viscous dampers on both sides of the ordinary activities of laminated rubber bearing, while bearing normal use, the bridge beam deflection temperature, due to the slow speed of temperature change bits , viscous dampers almost no resistance to displacement, and in the earthquake, viscous dampers in the role of rapid earthquake seismic force steel ball bearings, hardly displaced GKGZ seismic steel ball bearings, will have a significant displacement resistance, then the bridge bearing activities into a fixed bearing, so that all the piers of the bridge to bear the full force of the earthquake, achieve the purpose of shock absorption. Viscous damper damping medium, usually using ultra-high viscosity silicone oil WJGKQZ seismic steel ball bearings, to prevent leakage. Seismic steel ball bearings in general by the cylinder, piston and damping materials, the piston in the cylinder reciprocating do have the right amount of holes on the piston, cylinder built with viscous material. Structure under the action of earthquake seismic force and viscous dampers work together with the structure of import rod force, pushing the piston movement of the piston on both sides of the damping material produces a pressure difference, the damping medium through the orifice, resulting damping force, to energy dissipation purposes. The internal structure of the damper varies, the speed index is generally between 0.1 to 1.0. Also damping force also with the piston area, the orifice size and length, cheer frequency, temperature, and other factors related to the damping material category. Viscous dampers and PTFE sliding bearing combination is also a common relief isolators. Currently seismic steel ball bearings have been used for housing construction and some bridge structures, but because the seismic steel ball bearings in the event of bearing displacement, are accompanied by changes in seat height, so use a large cross with Continuous Beam Since a good seat on the temperature of each pier displacement vary, it will cause the pivot elevation varied from additional stress bearing. Currently used seismic steel ball bearings on Sutong Yangtze River Bridge. Seismic steel ball bearing LRB is the basis of a laminated rubber bearing on the center of the seat into the lead stick, in order to improve a seismic damping rubber bearing bearing performance. LRB bear the weight and the level of force structure WJGKGZ seismic steel ball bearings, the lead core to produce plastic deformation hysteresis damping and restoring force provided by the level of rubber. Seismic steel ball bearing metallic lead at ambient temperature in hot working conditions, when plastic deformation can lead gradually to restore the original mechanical properties. When the laminated rubber bearing steel and rubber to lead core tightly bound to live, forcing all of Lead in bearing shear deformation to produce plastic shear deformation, resulting in changes in the seat of hysteresis curves a holder having a good damping effect.
