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

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.

Studies on seismic reduction of multistory building using LRB to add stores;

Effects of Factors on the Bi-direction Seismic Response of LRB Isolated Bridge;

In the paper the influence of spatially ground motion on the longitudinal seismic response of isolated bridge with LRB(Lead Rubber Bearing) is presented.

The present paper gives a study on mechanical models of lead-rubber bearing (LRB) and seismic isolation effects by using LRB as isolation unit as well as how to choose it in real construction.
