Hysteretic modelling of steel wire mesh reinforced elastomeric isolation bearing

摘要：

　　The steel wire mesh reinforced elastomeric isolation bearing(SMREIB),which is made up of high-strength steel mesh and high-damping rubber,is a newly developed base isolation device for small-and medium-span bridges.This study presents a phenomenological model for the hysteretic behavior of this device under horizontal shear force based on a modified Ozdemir model with thirteen parameters which was identified from the quasi-static cyclic tests.The influences of these parameters on the shape of the hysteretic loop were numerically investigated.The equivalent stiffness and equivalent damping ratio of the device were evaluated.The presented hysteretic model is verified to perfectly fit the test measurements and will benefit the accurate computation of base-isolated bridge seismic response for design and performance evaluation.
