| 요약1 |
본 연구에서는 국가 시설물 내진대책으로서 납-적층고무받침(LRB)를 이용한 내진설계가 신뢰성 있는 유효한 수단으로 널리 인식될 수 있도록 국내의 지진환경, 지진격리장치 제작업체의 현황 등을 반영하여 실용성과 신뢰성을 갖춘 지진격리장치 성능평가를 위한 실험을 실시하였다. |
| 요약2 |
In this study, performance level evaluation tests have been actually performed on laminated rubber seismic isolation bearings (LRB) made in Korea. To provide basic data for setting up fabrication criteria and performance evaluation criteria three real scale LRB were tested and the test results were analysised. Accordingly, a large capacity test device has been designed and manufactured to implement the tests. The device selected for evaluation is a circular LRB actually applied in bridges. Evaluation tests were conducted using full-scale LRB with diameter of 851mm in the rubber part and total height of 215mm of which the effective horizontal stiffness and equivalent damping ratio have been measured during the experiments. |
