The fatigue is one of the key factors of long-lived design. For this study, wear & fatigue tests are carried out as per AASHTO Guide Specifications for seismic isolation design standard. In experiments, there was no appearance damage of the specimen. A study comparing test results before and after fatigue test showed that EDC & effective stiffness of the specimen after test is lower than before it.
