In Japan, Laminated rubber bearings have widely been used in road bridges after Kobe earthquake (1995). In Great East Japan earthquake (2011) and Kumamoto earthquake (2016), some damages were found in the bearings and they might be caused by tensile deformation. In this research, compressive and tensile hysteretic models of the bearings are developed. At first, we conduct loading experiments of single rubber layer, in order to grasp compressive/tensile behavior. Then, based on experimental results, we develop a tensile hysteretic model which combines an elasto- plastic unit and a damage unit in parallel. Finally, a compressive hysteretic model is constructed by adding a nonlinear elastic unit to the tensile hysteretic model in parallel. As a result, the proposed model is found to accurately reproduce the experimental results. |
