Research and Application of Lead-Disc Springs Isolator;

The 3DB was composed of Lead Rubber Beading (LRB) and Dish-Spring Bearing with damper (DBS) in series.

In this paper is introduced the three-dimension lead-rubber dish-spring bearing (3DB), composed of lead rubber bearing (LRB) and dish-spring bearing with damper (DSB) in series, which is found effective at vertical damping of 3D isolation bearing and suppressing oscillation.

Nonlinear seismic response analysis of aqueduct constructed with lead rubber bearing for vibration isolation;

On the basis of the thin-wall beam finite element model of an aqueduct with fluid-structure coupling,the seismic response of some large aqueduct is studied by use of the bilinear model and the Wen model to simulate nonlinear hysteretic curve of the lead rubber bearing.

Established a special base-isolation bearing unit,making use of unit stiffness matrix of the lead rubber bearing,obtained nine material constants of the orthotropic material unit by using back analysis.

In order to improve seismic performance of curved box girder bridge,based on spatial finite element method,nonlinear spring element was used to simulate the lead-rubber bearing(LRB) considering its nonlinear properties.

Based on the analysis of mechanical characteristics of lead-rubber bearings,using explicit finite element software ANSYS/LS-DYNA to analysis the nonlinear dynamic characteristics of lead-rubber bearings is presented.

In this paper, the lead-rubber bearings and viscous dampers are proposed to be used as the seismicity mitigation and energy dissipation devices at the connections between the deck and pylons of cable-stayed bridge.
