In this study, the seismic performance is evaluated through the effect analysis according to the before and after aging properties on laminated rubber bearing on the water tank retrofitted with laminated rubber bearing. As a result of this analysis, it was found that the changes in the basic properties of the laminated rubber bearing caused by the aging bring only a minor effect on the seismic performance of water tank.
