Modeling of Lead Rubber Bearings under Large Cyclic Material Strains

Lead rubber bearings (LRBs) have been widely used in seismic isolation systems for buildings and other structures to effectively mitigate the damaging effects of horizontal earthquake ground shaking. The horizontal flexibility of the LRBs, typically placed at the base of the structure, result in a concentration of displacements in the bearings while limiting deformations in the structure. Strong earthquake shaking can produce large displacement...
