Numerical Simulation of Steel-Laminated Bearing Considering Friction Slipping

Weiguo Huang, Xiuli Xu, Kairui Wang, and Weiqing Liu
Abstract—In order to obtain a more precise seismic response of steel-laminated elastomeric bearing, which is widely used in middle-span bridges, a three-dimensional finite element model of this bearing is built by ABAQUS software, incorporating material, geometric nonlinearities, and frictional contact between bearing surfaces and plates. Analytical simulation is carried out to study the behavior of steel-laminated elastomeric bearing under the compression and shear, adapting both penalty friction model and static-kinetic exponential decay friction model. The results about hysteretic curve and equivalent viscous damping ratio are compared with test one. The results show that the numerical results using static-kinetic exponential decay friction model are in good accordance with the test one, so the numerical model can simulate the behavior of experimental bearings well and is accurate enough to simulate the bearing friction slipping. Further parameter analysis on the influence of pressure and velocity of slipping is conducted, for bridge seismic design and analysis.

Index Terms—Steel-laminated elastomeric bearing, Analytical simulation, penalty friction model, static-kinetic exponential decay friction model.
