| Summary: | 碩士 === 國立高雄科技大學 === 營建工程系 === 107 === In the present empirical study, the traditional sliding isolation system has excellent isolation effect for far-field waves. On the other hand, the isolator displacement can be considerably enlarged in near-fault waves due to the long-period velocity pulse possessed in the near-fault waves. As a result, it may lead to a resonant motion that can reduce the effectiveness and safety of isolation. In order to improve the performance of the isolation system in near-fault waves,therefore, in this study, a multi-functional friction damper with two sets of activation mechanisms is added to the isolation system. After the numerical simulations and parameter analysis,the research shows that the isolation system with multi-function friction damper is beneficial to reduce the isolator displacement and structural acceleration under the near-fault waves. It can be proved that the addition of the multi-functional friction damper has good isolation effect in the isolation system.
